E. MICHAEL CAULFIELD
CHIEF EXECUTIVE OFFICER
PRUDENTIAL INVESTMENTS

DEAR CONTRACT OWNER:

We are pleased to provide our Semiannual Report to you on the investment
performance of the Portfolios that underlie your DISCOVERY SELECT-SM- Variable
Annuity contract.

Once again, the news is outstanding. In the first half of this year, stock
prices surged nearly 21%, about two times the typical average in a full year. In
fact, the Dow Jones Industrial Average broke through 8000 on July 16, two weeks
after the end of the first half. This certainly was not what most Wall Street
experts had predicted.

Bonds, too, performed favorably in the first half of 1997. Bonds returned 3.1%
over the last six months, as measured by the Lehman Brothers Aggregate Index.
Corporate high yield bonds in general were the strongest, returning 5.8% for the
period.

What led to such excellent performance? Conditions were idyllic for most
investors in the first half -- economic growth was strong and interest rates
were relatively stable, so corporate profits rose. Unemployment fell to a
23-year low and consumer confidence hit a 28-year high.

IT'S LONG-TERM PERFORMANCE THAT COUNTS.

Although in this report we're focusing primarily on performance for the first
half of this year, remember that it's long-term performance that counts. Review
your Portfolio's performance so far in 1997, but also be sure to note its
longer-term record. You'll note that over the past three, five and 10 years many
of our Portfolios have delivered excellent performance, both on an absolute
basis and in comparison with funds having similar objectives.

Our goal is to achieve this kind of above-average investment performance over
time. Such consistency is important, because most people buy variable annuities
to finance long-term goals. So when you consider how to allocate either new or
existing assets among these Portfolios, please look closely at their performance
over five and 10 years as well.

- --------------------------------------------------------------------------------
"Conditions were idyllic for most investors in the first half --
economic growth was strong and interest rates were relatively stable, so
corporate profits rose."

COULD THE THIRD TIME BE A CHARM?

When the U.S. stock market rose 37% in 1995, we doubted it would be repeated any
time soon. Then stocks advanced 23% in 1996. We thought it unlikely that this
kind of performance would be duplicated again. And now, through the first half
of 1997, stocks are already up nearly 21%.

It's clear that we -- and, we venture, most other investors -- cannot predict
the stock market. Nevertheless, it's even more important now to remember that
the U.S. stock market now sits at valuations beyond all historic boundaries.

Now, more than ever, your asset allocations should be based on reasonable
expectations for those asset classes, not the most recent performance. What's
reasonable? Well, over the last 70 years the average annual return of U.S.
stocks is 10.7% as measured by the Standard & Poor's 500 Composite Stock Price
Index.

With this in mind, you may want to reevaluate how you allocate your money among
the DISCOVERY SELECT investment options. While stocks ought to remain the
investment of choice for most investors looking for long-term wealth
accumulation, now might be a good time to consider diversifying a portion of
your holdings. If you wish, contact your Prudential Securities Financial
Advisor/Pruco Securities Registered Representative for assistance in structuring
a program to help meet your needs.

All of us at Prudential thank you for your business and look forward to helping
you plan for your future financial security.

IMPORTANT NOTE

The rates of return quoted on the following pages reflect the deduction of
investment management fees and investment-related expenses, but not product
charges. They reflect the reinvestment of dividend and capital gains
distributions. They are not an estimate or a guarantee of future performance.

Contract unit values increase or decrease based on the performance of the
Portfolio and, when redeemed, may be worth more or less than their original
cost. Changes in contract values depend not only on the investment performance
of the Portfolio but also on the insurance and administrative charges,
applicable sales charges, and the mortality and expense risk charge applicable
under the contract. These contract charges effectively reduce the dollar amount
of any net gains and increase the dollar amount of any net losses.

Your Prudential Securities Financial Advisor/Pruco Securities Registered
Representative can provide you with actual rates of return for your DISCOVERY
SELECT-SM- Variable Annuity and show you a personalized illustration of how
charges affect the returns you experience.

1997 MARKET REVIEW

U.S. STOCKS

THE DOW: 6600, 6800, 7000, 7200, 7400, 7600 . . .

After rising 37% in 1995 and 23% in 1996, stock prices rose another 21% in the
first six months of 1997. This stunning performance prompted analysts and
economists alike to reach for superlatives.

The wonder was the economy. The current U.S. economic expansion is now in its
seventh year, the third longest in history. Unemployment is at its lowest since
1973. Inflation seems like a distant memory. All of this means higher corporate
revenues and stable corporate borrowing costs -- and as a result, higher
corporate profits. It's a nearly idyllic investment environment.

To be sure, the stock market did not rocket straight up in the first half of the
year. Stocks actually fell nearly 10% in the spring, amid short-lived fears of
higher interest rates. Back in March, the Federal Reserve increased short-term
interest rates (by a quarter of a percentage point), for the first time in two
years. The nation's central bankers feared that first-quarter economic growth
would set off a new round of inflation. Stocks recovered in April amid evidence
the growth rate was moderating.

LARGE STOCKS WERE THE LEADERS, AGAIN.

In the first half of the year, the biggest stocks were the best performers. The
five biggest companies in the S&P 500 gained 34% in the first half of the year,
while the top 25 companies gained 28%. Of the largest companies, the drug stocks
seemed to do the best as a group, with Warner Lambert up 67%, Eli Lilly rising
51%, Bristol-Myers Squibb climbing 49% and Pfizer advancing 45% during the
period.

Small company stocks trailed larger companies, as they have for several years
now, rising 10% in the first half of 1997 as measured by the Russell 2000*.
(These companies are generally defined as those whose outstanding stock is
valued at less than $1 billion.) Still, performance of these stocks has been
improving in recent months. Consumer growth stocks (powered by the
pharmaceutical companies) led the market, followed by financial and consumer
cyclical stocks (auto, retail and housing stocks whose fortunes tend to mirror
the ups and downs of the economy).

THIS CHART COMPARES THE 6-MONTH RETURN AS OF 6/30/97 FOR VARIOUS CATEGORIES OF
INVESTMENTS WITH THE AVERAGE ANNUAL TOTAL RETURN OVER 20 YEARS FOR THE SAME
INVESTMENT. AS YOU CAN SEE, STOCK AND BOND MARKET RETURNS CAN VARY CONSIDERABLY
FROM YEAR TO YEAR. UNLIKE STOCKS, BONDS GENERALLY OFFER A FIXED RATE OF RETURN
AND PRINCIPAL IF HELD TO MATURITY. AN INVESTMENT'S PAST PERFORMANCE SHOULD NEVER
BE USED TO PREDICT FUTURE RESULTS. THERE ARE DIFFERENT RISKS ASSOCIATED WITH
EACH INVESTMENT SECTOR, WHICH SHOULD BE CAREFULLY CONSIDERED BEFORE INVESTING.

GUARANTEE OF FUTURE RESULTS.

CONSUMER GROWTH stocks rose almost 25% during the first half of 1997, powered
primarily by drug companies, beverages and household products. As stock prices
rose higher and higher, investors seemed to favor the very largest companies
that produce the most steadily predictable earnings and therefore stocks that
can be traded most easily. Widely owned Coca-Cola rose 30%. Another household
name, Gillette, rose 22%.  Drug companies also did well, as previously
mentioned.

FINANCIAL stocks climbed nearly 24% for the period. Mergers and acquisitions
among financial companies continued to dominate (such as Morgan Stanley and Dean
Witter), helping to fuel interest in this area. A feeling that the Federal
Reserve would not raise short-term interest rates any further helped power bank
stocks higher.

1997 MARKET REVIEW CONTINUED

U.S. BONDS

INTEREST RATES: SOMEWHAT STABLE.

Long-term interest rates rose, then fell, in the first half of the year, ending
slightly higher at midyear. The Federal Reserve raised short-term interest rates
for the first time in two years, lifting the overnight bank lending rate by a
quarter of a percentage point in March to 5.5% as a precaution against
too-strong economic growth. In response, long-term interest rates at first rose.
Rates later eased as inflation worries subsided, along with concerns of further
action by the Federal Reserve.

Bonds returned 3.1% over the first six months of 1997 as measured by the Lehman
Brothers Aggregate Index. The yield on the bellwether 30-year U.S. Treasury bond
rose to 6.78% on June 30, 1997, from 6.64% on December 31, 1996. Short-term
rates, as measured by the three-month U.S. Treasury bill, actually fell
slightly, to 5.17% on June 30, 1997.

Corporate high yield bonds in general were the strongest, returning 5.8% for the
period. High yield corporate bonds fared well on solid economic growth, rising
corporate profits, minimal defaults and powerful demand as a broadening base of
institutional investors seeking higher yields became interested in this sector.
A large number of new issues were sold in the first half -- $55 billion -- only
$8 billion less than in all of last year. Better-rated high yield securities, as
a group, outperformed those with poorer credit ratings.

Solid economic growth, stable inflation and steady governments also helped
emerging markets' bonds to a strong first half. Argentina led all of Latin
America, rising 11% as financial stability in the region improved generally.
Brazil, Mexico and Venezuela followed, as reported by Morgan Stanley.

FOREIGN STOCKS

EUROPE STRONG; JAPAN AND PACIFIC REGION REBOUND.

Although stock markets in Europe and the Pacific couldn't match the
torrid performance of the U.S. market in the first half of 1997, European stocks
were strong and Pacific stock markets -- especially Japan, which represents
two-thirds of the region -- came alive in the second quarter.

In the Pacific, returns for the full first six months of the year were
comparatively subdued: Pacific stocks rose 7% and Japanese stocks climbed 9%.
But these returns masked a 24% gain by Japanese stocks for U.S. investors in the
second quarter, because the yen strengthened significantly against the U.S.
dollar.

LET'S DO EUROPE.

Europe was the best region outside the United States in the first six months (as
measured in dollars), as stocks of many more-efficient export-oriented companies
led markets higher. European stocks in general have benefited from the movement
toward monetary unity in 1999, which has forced governments to economize,
reducing interest rates. Export-oriented companies fared best, rising in the
second quarter.

JAPAN RISES.

A strengthening yen powered Japanese stocks to their highest levels since
December, igniting gains throughout the Pacific region. The U.S. dollar lost 12%
against the yen in just five weeks in May and June. This helped Japanese stocks
rise 24% for U.S. investors in the second quarter. But because Japanese stocks
had lost ground in the first quarter of 1997, they were ahead only 9% in U.S.
dollars for the first half of the year.

Hong Kong stocks also performed well, as investors overcame their fear of
turning over the British colony to China after more than 150 years.

1997 PRUDENTIAL'S OUTLOOK

THE ECONOMY.

Our economists at Prudential suspect that growth will remain relatively subdued
for the rest of the year. Economic growth slowed sharply in the second quarter.

They also expect inflation will remain benign, below 3%. As a result, the
Federal Reserve will likely refrain from raising short-term interest rates any
further this year, and the central bankers may ultimately lower rates by early
next year, our economists predict.

U.S. STOCKS: WHAT'S AFTER 8000?

Now that the Dow Jones Industrial Average has hurdled 8000, with some analysts
now predicting a Dow of 10,000, it's only natural to wonder how long all this
good news can continue. After all, stock prices have doubled in the last two and
a half years.

At these high price levels, stock selection is even more crucial. So, too, is
understanding the objective, strategy and risks of the portfolio in which your
contract values are invested. Some stocks now sell at very high prices --
particularly those of large, well-known companies. But other stocks remain
attractive. Some of our managers like industrial companies, real estate
investment trusts and securities brokerages, because they believe they have room
to appreciate. Others like insurance, paper and retailing, thinking they are
undervalued. Our growth stock managers who have done very well with the
pharmaceuticals, also think that technology is due for an upswing after hitting
what seemed like a bottom in April.

BONDS: WE'RE SEARCHING FOR YIELD.

We suspect that prices in the bond market will remain relatively stable through
the rest of the year, depending on the relative weakness or strength that
investors see in the economy.

We are focusing now on finding bonds that provide more yield than U.S. Treasurys
while offering comparatively little additional risk.

We are particularly interested in crossover bonds -- those with split ratings of
investment grade (BBB) by one rating agency and just below investment grade (BB)
by another. Frequently, we can buy these bonds at more attractive prices than
bonds rated below investment grade (high yield bonds), because of the
uncertainty over their credit strength.

We are also interested in emerging markets. Relative stability in governments,
economic growth and low inflation made emerging markets' bonds the
best-performing bonds in the world in the first half of the year. We've added
Russian, South African, Panamanian and Polish bonds, among others, to our
portfolios.

FOREIGN STOCKS: LOOK FOR THE JAPANESE SURPRISE.

The Japanese stock market may be a pleasant surprise this year. We've
purchased stocks of domestically oriented Japanese companies that sell their
products and services within the country; they are more attractively priced than
export-oriented multinational companies.

In Europe, we see the opposite. We are invested in multinational stocks,
particularly those that are restructuring to increase efficiency. We believe
that the movement toward a common European currency will continue to constrain
economic growth rates within Europe, so we are most interested in companies
listed on European stock exchanges but that derive most of their revenues from
outside Europe.

In Hong Kong, we suspect that the new Chinese control will limit the escalation
of real estate prices. Since property-related stocks are about a third of the
market index, prices in general will have to struggle to move higher.

- --------------------------------------------------------------------------------
A REALITY CHECK.

Stock prices in general have nearly doubled in the last two and a half years.
We're quite pleased with the unusually high returns that stocks have provided
for our Contract Owners over the past few years, and we are certain that you
are, too. Those types of returns bring you closer to your goals of financial
security faster than you might have expected.

Since 1926, the U.S. stock market's average return has been 10.7%, as measured
by the S&P 500. Yet, in recent years, returns have been much higher, as the
chart below shows.

PRUDENTIAL MONEY MARKET PORTFOLIO

PERFORMANCE SUMMARY.

Your Portfolio got off to a solid start in 1997. On June 30, 1997, your
Portfolio's 7-day yield was 5.36%, up from 5.15% on December 31, 1996. Its
return of 2.61% for the first six months exceeded the 2.47% return of the
average money market fund tracked by Lipper Analytical Services.

Interest rates started to rise late in the first quarter when economic activity
accelerated. In March, the Federal Reserve increased the overnight bank lending
rate. Since then, yields have fallen amid signs of moderating U.S. economic
growth and a belief that the Federal Reserve will not raise interest rates again
for some time. Indeed, the central bank voted to hold rates steady at its
meetings on May 20 and July 2.

During this period of fluctuating interest rates, the Portfolio's performance
benefited from a decision to hold a mixture of very short term securities to
take advantage of rising interest rates and longer term money market securities
to lock in higher interest rates.

An investment in the Money Market Portfolio is neither insured nor guaranteed by
the U.S. government. There is no guarantee that the Portfolio will be able to
maintain a stable share value of $10.00.

INVESTMENT GOAL

Current income, stability of capital and maintenance of liquidity.

TYPES OF INVESTMENTS

Short-term money market securities that generally mature in 13 months or less.
These securities primarily consist of Certificates of Deposit (CDs); Commercial
Paper and Bankers' Acceptances, U.S. Treasury bills (T-bills) and other
instruments issued by or guaranteed by the U.S. government or its agencies.

PERFORMANCE REVIEW.

READY FOR THE RATE RISE. Late in the first quarter, Federal Reserve officials
began hinting that the central bank might act preemptively to slow economic
growth and keep inflation in check.

We heeded the warnings and began preparing your Portfolio for the possibility of
a rate increase by investing in very short-term securities. At the same time, we
purchased one-year corporate obligations in order to take advantage of the
recent rise in yields on these securities.

As expected, the central bank raised the rate banks pay to borrow funds by a
quarter of a percentage point, to 5.5%, on March 25. This was the first interest
rate rise in two years.


                                          10

<PAGE>

STRATEGY SESSION.

A TWO-PRONGED APPROACH. Expecting a Federal Reserve interest rate increase in
March, we focused on one-month and one-year money market securities as well as
securities whose coupons adjust periodically with changes in the London
Interbank Offered Rate (LIBOR).

Investing in the one-month sector allowed the Portfolio to reinvest those assets
in higher-yielding securities once the Federal Reserve increased shortterm
interest rates. Meanwhile, we also invested in higher-yielding corporate
obligations such as bank notes and CDs that mature in a year.

Although the U.S. economy grew rapidly in the first quarter, later reports on
retail sales, housing starts, producer and consumer prices indicated economic
growth eased in the second quarter and inflation remained tame.

The retail sales data are especially important, because consumer spending
accounts for two-thirds of gross domestic product in the United States. With the
U.S. economy apparently growing more slowly, interest rates edged lower in the
second quarter. As a result, the one-year corporate obligations we purchased
have appreciated in value.


OUTLOOK 
PORTFOLIO MANAGER
MANOLITA BRASIL

GUARDEDLY OPTIMISTIC.

"I remain cautious. Unemployment is near historic lows, and although economic
growth appears to have slowed in the second quarter, the economy continues to
operate at a high capacity.

"So if consumers start buying again and demand rises, I believe the Federal
Reserve will feel compelled to raise interest rates. I think in the third
quarter, if demand picks up and job growth remains high, the Fed will raise
interest rates by another 25 basis points. If demand does not pick up and
inflation continues to be favorable, as it has been, then the Federal Reserve
will most likely keep interest rates where they are now."

PRUDENTIAL DIVERSIFIED BOND PORTFOLIO

PERFORMANCE SUMMARY.

Your Portfolio performed better than its benchmarks in the first six months of
1997. With a six-month return of 4.11%, your Portfolio easily beat the 3.07%
total return on the average Lipper (VIP) Corporate Debt portfolio and the 3.09%
return of the Lehman Aggregate Index.

We were helped by our sizable holdings in corporate bonds, including those from
the media and cable industry. We also held higher-yielding U.S.
dollar-denominated bonds issued by foreign governments such as Mexico,
Argentina, Panama, Venezuela and South Africa.

Your Portfolio has performed better than the average corporate debt fund in
variable life and annuity products over the past one, three, five and 10 years.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risks of currency fluctuation and the impact of social, political and
economic change.

INVESTMENT GOAL
High level of income over the long term while providing reasonable
safety of capital.

TYPES OF INVESTMENTS
U.S. government securities, mortgage backed bonds, both investment-grade and
high yield ("junk bond") corporate debt, and foreign securities (dollar and
non-dollar denominated).

INVESTMENT STYLE
This Portfolio seeks the highest yield while maintaining safety of capital, by
strategically allocating Portfolio assets among the above classes of bonds.

PERFORMANCE REVIEW.

WINNING CHOICES. Bond prices fell and interest rates rose both before and after
the Federal Reserve raised the overnight bank lending rate by a quarter of a
percentage point to 5.5% on March 25 to keep the economy from fueling higher
inflation. (Prices on older bonds typically fall as interest rates rise, because
newly issued bonds will carry higher coupons.)

Still, your Portfolio achieved exceptional results, primarily because we
carefully selected corporate bonds that performed well even though interest
rates rose somewhat. These bonds responded more to solid corporate earnings and
a lower-than-expected volume of new bond issues. With fewer bonds from which to
choose, prices on those available tended to gain.

STRATEGY SESSION.

SPOTLIGHT ON MEDIA AND CABLE BONDS. We focused on bonds issued by companies in
the media and cable industry. Our holdings in Time Warner Inc. and
Telecommunications Inc. appreciated markedly as their financial positions
improved. For example, Time Warner reported that its cash flow surged a hefty
16% during the first quarter of 1997. Telecommunications, Inc. is reducing debt
on its balance sheets and increasing cash flow by reducing capital expenditures
and expenses.

A new type of preferred security called a preferred trust security was first
sold in the market in November 1996 by some banks and insurance companies. These
were priced inexpensively to attract investors, so we bought them. We were not
disappointed, because prices have risen markedly since they were first issued.

KNOWING WHEN TO STAY PUT. Your Portfolio also performed well because we did not
try to predict the course of interest rates, which proved very volatile in the
first half of the year. We kept duration, a measure of the Portfolio's
sensitivity to changes in interest rates, in a tight range of 5.1 years to 5.3
years during the period.

The shorter the duration, the more the Portfolio's value is protected when
interest rates climb. So your Portfolio suffered only minimally when the Federal
Reserve raised the overnight bank lending rate, but its value improved as bond
prices rose in June.

CROSSOVER CREDITS.

"Corporate bond issuance has been heavy, and given the positive performance in
the stock market and the reduced supply of government bonds, we've held more
corporate bonds than usual and have tried to pick the more attractive
opportunities in the market.

"Many of these companies are known as crossover credits, because at least one
rating agency considers them investment grade while another rater does not. By
investing in these bonds, we have kept both the yield and the quality of the
Portfolio relatively high. At the same time, we've been able to avoid holding
too many higher-yielding bonds that are of lower quality."

PRUDENTIAL HIGH YIELD BOND PORTFOLIO

PERFORMANCE SUMMARY.

Your Portfolio returned 5.88% for the first six months of 1997, slightly lagging
behind the 6.10% return on the average high yield bond fund tracked by Lipper
Analytical Services. Although market conditions were generally favorable for
high yield bonds, the Portfolio's performance trailed our benchmark because we
focused on the telecommunications and cable industries, which did not perform as
well as other industries.

In addition, high yield bonds slumped along with other bonds as interest rates
rose in March and April, then rebounded later as the bond market recovered.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risks of currency fluctuation and the impact of social, political and
economic change.

INVESTMENT GOAL
High total return.

TYPES OF INVESTMENTS
Primarily noninvestment-grade bonds. These bonds have speculative
characteristics and are subject to greater credit and market risk than
higher-quality securities.

INVESTMENT STYLE
Concentrates primarily on junk bonds that appear to offer an attractive
combination of high current income and attractive total return.

PERFORMANCE REVIEW.

AN INCREASE IN RATES AND NEW BONDS. Investors pushed interest rates higher and
bond prices lower both before and after March 25, when the Federal Reserve
increased the overnight bank lending rate by a quarter percentage point to 5.5%
to prevent a pickup in inflation. As a result, prices of high yield bonds fell.

The Portfolio's performance was constrained by its holdings in
telecommunications and cable bonds. A large new supply of these bonds issued in
the first quarter depressed prices, because supply exceeded demand from
investors. Still, high yield bonds improved in the second quarter as the bond
market bounced back when interest rates fell as inflation fears subsided.

STRATEGY SESSION.

SOME GOOD NEWS. We continued to emphasize bonds of large companies, particularly
those that may become involved in mergers and acquisitions or could become
candidates for a credit upgrade. In the second quarter, a flurry of good news
enabled two of our holdings -- Cablevision Systems and Comcast -- to fare
particularly well.

Cablevision Systems bonds appreciated in value after an announcement that News
Corp. and Telecommunications, Inc. will pay $850 million for a 40% stake in the
sports television business of Cablevision Systems to create a national chain of
cable television sports channels.

Comcast bonds benefited from a $1 billion investment by Microsoft to speed up
development of a two-way, broadband fiber-optic network. In fact, a credit
rating agency upgraded Comcast senior subordinated debentures and convertible
subordinated debentures in June, citing its improved financial flexibility.

CUTTING HERE, ADDING THERE.

"We are taking advantage of the recent rally in cable and telecommunications
bonds to sell some of our holdings to reduce our emphasis on those sectors to a
level that is closer to the market indices.

"We like the outlook for the bond market and particularly the high yield market
for the remainder of the year. As a result, we are reducing the Portfolio's cash
position by investing in new issues and attractive secondary offerings."

PRUDENTIAL STOCK INDEX PORTFOLIO


PERFORMANCE SUMMARY.

Your Portfolio finished the first half of 1997 with a return of 20.32%, an
upward sweep similar to the climb in the preceding two years, except for a
decline in March. The S&P 500 Index returned 20.6%.

Foreign investors and individual investors using mutual funds have poured cash
into the U.S. stock market, helping to power its prolonged climb. The demand for
S&P 500 stocks has driven up their prices even faster than earnings have risen.

The result is a market that has performed so well for so long that many
investment professionals doubt it can continue. For example, the S&P 500 Index
has become increasingly volatile recently and is particularly vulnerable to
earnings disappointments.

Standard & Poor's neither sponsors nor endorses the Stock Index Portfolio.
Investors cannot directly invest in any index, including the S&P 500.

PERFORMANCE REVIEW.

The Stock Index Portfolio attempts to duplicate the performance of the S&P 500
Index by holding all 500 stocks in the index. Portfolio Manager John W.
Moschberger manages the Portfolio by investing funds received, while trying to
minimize commissions and transaction costs.

A GALA OF GOOD NEWS DROVE UP PRICES. The market for large-capitalization stocks
resumed its steep climb at the end of April, after slowing in anticipation of
higher interest rates and an economic slowdown. Fears that interest rates would
rise abated when the economy showed only moderate growth rates, obviating any
action by the Federal Reserve to cool it down. This good news was accompanied by
first-quarter earnings reports that averaged about 18% higher than a year
earlier. With consumer confidence at a 28-year high and unemployment at its
lowest since 1973, the investment environment seemed idyllic.

FINANCIALS AND TECHNOLOGY JOINED BY CONSUMER GROWTH. The rise in the second
quarter was powered by the rebound of the technology sector from its
stutter-step earlier in the year, with energy and industrials also doing well.
For the year-to-date, consumer growth and staples, finance and consumer
cyclicals were the leading sectors. Savings and loans as a group led the market.
Computer software and services, drugs and medical supplies, and the trucking and
shipping industry all rose by more than a third in just the half year.

UTILITIES STILL UNDERPERFORMING. Stocks for all sectors except utilities
averaged double-digit gains for the half year. Utilities are facing competition
and dramatic restructuring. Investors have not been enthusiastic about the
uncertainties.

A few scattered industries turned down, on average: gold, lodging, gaming and
energy exploration.

PRUDENTIAL EQUITY INCOME PORTFOLIO


PERFORMANCE SUMMARY.

Your Portfolio returned 17.47% over the past six months, above the Lipper (VIP)
Equity Income Average of 16.83%. Performance for the past 12 months, 33.59%,
also exceeded the average of comparable portfolios.

We use a bottom-up investment style and, in some cases, the performance of one
or two companies in a sector made significant contributions to performance this
half. Stock selection within the energy, technology and utility sectors
accounted for the good results.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risks of currency fluctuation and the impact of social, political and
economic change.

INVESTMENT GOAL
Current income and capital appreciation.

TYPES OF INVESTMENTS
Primarily stocks and convertible securities with prospects for income returns
above those of the S&P 500.(3)

INVESTMENT STYLE
The Portfolio uses a "value" investment approach to companies that are
attractively priced relative to book value, earnings, discretionary cash flow,
sales and other measures of value.


PERFORMANCE REVIEW.

AN OIL SERVICE COMPANY IS LIKELY TO RESTRUCTURE. We expected McDermott
International to improve earnings by restructuring. A change in management made
this more likely, and also more apparent to investors, who pushed its stock
price higher.

TWO PRIVATIZED UTILITIES MOVED UP. We enjoyed excellent gains from a privatized
Latin American telephone company that had been undervalued by the market and is
now moving closer in price to similar companies. A British private utility faces
a friendlier rate structure that rose almost 40% in the half year.

We also took gains on semiconductor stocks in the first quarter.

STRATEGY SESSION.

REITs OFFER STEADY DIVIDEND GROWTH. REITs (real estate investment trusts) buy
real estate and issue shares to the public, making it easier for individuals to
invest in the burgeoning real estate market. Ease of ownership increases the
pool of buyers and should push prices up. In addition, REITs have high dividend
yields at current prices and also offer the prospect of predictable dividend
growth. We believe that the market currently undervalues this attractive
feature.

SECURITIES BROKERAGES ARE IN PLAY. Thanks to changes in the regulatory
environment, securities brokerages have become takeover targets. We expected
consolidation and still do. Lehman Brothers, among our largest holdings, rose
almost 30% in the past half year. We bought our securities company holdings
cheaply and have seen nice gains. Nonetheless, they are still inexpensive in
comparison to their current earnings.

CONSUMER DEMAND MOVES UP THE CHAIN. We think pricing power is swinging from
consumer companies back toward the industrial companies that service them. So
far this has kept us from participating fully in the gains of the consumer
growth sector, but we expect it to pay off down the road.

OUTLOOK 
PORTFOLIO MANAGER
WARREN E. SPITZ

SECURITIES FIRMS ATTRACTIVELY PRICED.

"Although the market prices of securities firms already have risen, we still
find them attractively priced compared with other financial firms. A dollar of
investment buys a relatively large amount of current earnings and also offers
solid exposure to the stock market.

"The market seems to be undervaluing these firms out of fear that their earnings
will fall if a long-term bear market occurs. With economic growth steady and
corporate earnings exceptionally high, that doesn't seem imminent. Moreover, the
industry is likely to consolidate before the stock market turns.

"The synergism of brokerages with other financial services makes them very
attractive as acquisition or merger candidates. There are many financial
services companies looking to buy securities firms and relatively few large
brokerages to buy. They have scarcity value. Right now, we think that makes an
attractive package."

PRUDENTIAL EQUITY PORTFOLIO


PERFORMANCE SUMMARY.

Your Portfolio returned 13.26% in the first half of 1997, slightly below the
Lipper (VIP) Growth Fund Average of 13.57%. Historically, your Portfolio has
outperformed similar funds over the past one, five and ten years, as reported by
Lipper Analytical Services, Inc.

During the first half, we held about 25% of your Portfolio in cash. While this
dampened our recent returns, our value discipline demands that we only purchase
demonstrably "cheap" securities. There are very few of these in today's market.
Our cushion also provided some protection when the market took a stutter-step at
the end of the first quarter.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risks of currency fluctuation and the impact of social, political and
economic change.

INVESTMENT GOAL
Capital appreciation.

TYPES OF INVESTMENTS
Primarily stocks of major, established companies.

INVESTMENT STYLE
This Portfolio uses a "deep value" investment approach to invest in stocks
believed to be temporarily undervalued relative to the companies' sales,
earnings, book value and cash flow.

PERFORMANCE REVIEW.

INSURANCE COSTS. Currently, share prices are very broadly high, and these prices
have been sustained by first-quarter earnings reports up about 18%, on average,
over a year earlier. Nonetheless, since mid-1994 stock prices have risen
substantially faster than their underlying earnings. Rarely have stocks been
this richly valued compared to bonds.

To make matters worse, the "cheap" stocks are currently not particularly
inexpensive compared to the average stock. Our time-tested investment discipline
tells us not to buy when prices are high.

The likelihood of above-average returns is limited and the risk of a price
decline is comparatively high. We're ready to buy as soon as some patches of
inexpensively priced companies appear.


                                          20

STRATEGY SESSION.

We've cut back our holdings in financial services, modestly reducing our
exposure to the banking industry. After severe lending problems in the early
1990s, the banking industry has come surging back to record profitability. While
the stocks remain relatively inexpensive compared to the overall market, they
would likely prove vulnerable to any change in the very favorable operating
environment they have been enjoying for the last several years.

We also cut back our holdings in American Express. The turnaround at the company
has been impressive and it has been accompanied by a sharp increase in the
market's assessment of its value. Although the stock still is slightly cheaper
in relation to earnings than the average company, the higher price argues
against maintaining as large a position as we have had.

Some of the proceeds from these sales were invested in health stocks and in food
and restaurant companies.


OUTLOOK 
PORTFOLIO MANAGER
THOMAS R. JACKSON

DISCIPLINE COUNTS.

"Research shows that two basic investment styles, value investing and growth
investing, alternate in relative advantage, often for a few years at a time. For
the last couple of years, large-capitalization growth stocks such as Microsoft,
Intel, Coca-Cola, Cisco Systems, Merck and General Electric have been leading
the market. As the economic cycle has aged, high earnings growth has become
scarce and investors have concentrated on a relatively limited universe of
companies. As a result, these companies have been bid to very high levels, in
many cases levels that have not been seen since the early seventies. Even if
their earnings continue to grow, investors are paying a very high price for
those prospects.

"Value investors look for companies that sell at large discounts from the
average company, either because their strengths aren't appreciated or because
they are in a temporary earnings depression. We look for companies that sell at
low price/earnings ratios, price/book value ratios and price/cash flow ratios.
However, the long bull market has pushed up prices of almost all companies with
reasonable earnings prospects, leaving little for the disciplined value manager
to purchase.

"Research also shows that historically it has been wise to stick to one
investment style. Disciplined investors do better in the long run, whatever
their style. We believe that it is better to have exposure to both the growth
and value investment styles over the long run, rather than trying to switch
between the two. With this in mind, we are sticking to our discipline: not
buying expensive companies just because they are the only companies for sale and
keeping a cash supply to invest when good values appear."

compares with an increase of 13.57% for the Lipper (VIP) Growth Average. Your
Portfolio has outperformed similar funds since its inception in 1995.

The period was especially volatile, as the S&P 500 declined early in the year,
only to recover to new highs by the end of June. Many of the technology stocks
that turned in disappointing performances during the first quarter rebounded in
the second, resulting in strong six-month numbers from this sector. Health care
stocks were also significant contributors to performance during the period.

The Portfolio may invest in foreign securities. Foreign investments are subject
to the risks of currency fluctuation and the impact of social, political and
economic change.

INVESTMENT GOAL
Long-term growth of capital.

TYPES OF INVESTMENTS
Primarily common stocks of established companies with above-average growth
prospects.

INVESTMENT STYLE
This Portfolio uses a "growth" investment style to invest in the common stocks
of both mid-sized and large companies.


PERFORMANCE REVIEW.

The Portfolio invests in medium to large companies whose earnings we expect to
grow faster than the market average. Historically, this has been a favorable
investment strategy. Investors in the current market environment have put a high
premium on consistency, as shown by the performance of the large-cap S&P 500
Index versus the broader Wilshire 5000 Index.

WINNERS: The Portfolio benefited from its positions in rapidly growing
technology companies such as Dell Computer and Microsoft Corp. and global
pharmaceutical companies such as Bristol-Myers Squibb Co. and Eli Lilly & Co.

LOSERS: Technology also hurt the Portfolio performance, as networking companies
3 Com and Ascend Communications declined in value, reflecting the intense
competition and consolidation in that industry. In contrast, networking stocks
provided some of the best rates of return in the technology sector during 1996.

STRATEGY SESSION.

As evidenced by our high weighting in the technology sector, we remain convinced
of the potential returns available in this area. Technology is one of the
fastest-growing parts of the economy, as demand for personal computers,
software, cellular phones, pagers, etc. remains high.

Technology also benefits from the tendency of the prices of these products to
fall over time, causing an expansion in the size of their potential markets.
However, investing in technology can be unsettling in the short term, as the
expectations of investors can change rapidly. In addition to technology, both
consumer companies and financial firms appear to offer high potential earnings
gains over the intermediate term of 12 to 18 months.

As the S&P 500 has increased more than 100% since early 1995, volatility will
remain high. However, we believe we have constructed a high-quality portfolio of
rapidly growing companies whose stocks offer significant return potential over
the next one to two years, especially in this environment of surprisingly low
inflation and steady, but slow, growth.


OUTLOOK 
PORTFOLIO MANAGER
DAVID T. POIESZ

SOLID GROWTH PROSPECTS.

"The equity markets continue to be buoyed by the moderating growth in the
economy, which has given the Federal Reserve room to breathe easier and has
allowed long-term interest rates to move lower. The Federal budget balancing
agreement and tax cuts bode well for a continued solid equity market with the
best performing stocks likely being those which exhibit solid earnings growth
prospects. We are finding many attractively valued stocks with solid or
improving earnings growth prospects, despite the market's high valuation."

INVESTMENT GOAL
Long-term growth of capital.

TYPES OF INVESTMENTS
Primarily common stock and common stock equivalents of U.S. and foreign
corporations.

INVESTMENT STYLE
This Portfolio uses a "growth" investment approach, coupled with a
theme-oriented view of the markets, to identify companies that seem best
positioned to take advantage of global changes.


PERFORMANCE REVIEW.

THE U.S. AND EUROPEAN STOCK MARKETS WERE BUOYANT. In Europe, we emphasized
companies that have strong international revenues and companies that can
leverage large earnings gains from small increases in sales. Our relatively
light holdings in the U.S. were concentrated in technology stocks, which took a
stutter-step in the first quarter but finished the half on an upswing.

JAPAN CHANGES COURSE. We had de-emphasized Japan, where stocks fell sharply in
the first quarter. We avoided the financial sector, where the worst damage
occurred, and were adding domestically-oriented stocks when the Japanese market
rebounded. We did exceptionally well in Japan this period, and in the smaller
Pacific countries as well.

THE MEXICAN MARKET ROSE SHARPLY. Our investments there also served us well, as
its free-market economy strengthened.


                                          24

STRATEGY SESSION.

GOOD FOR PRODUCTION, NOT FOR SALES. In Europe, we focused on well-managed
companies, many of which had recently reorganized to improve productivity. We
preferred companies that were selling into the world market, where they could
profit from economic acceleration anywhere. European growth has been slow for
some time, resulting in high unemployment, which restrained labor costs and
domestic sales revenues. So we own companies that produce in Europe and sell
primarily elsewhere.

We also look for companies where small increases in sales can produce
disproportionate increases in earnings. For example, we like software companies,
firms that have been through productivity-increasing reorganizations and
manufacturers of telecommunications equipment.

JAPAN'S DOMESTIC MARKET LOOKS UP. We began 1997 underrepresented in Japan, with
a strategy there much like our European strategy. But now we expect more
domestic economic activity in Japan, where the government appears to be
committed to encouraging greater productivity in industries that historically
have been protected from competition. Moreover, in part because the yen has
declined substantially from its highs, Japanese consumers have been spending
less abroad. What's more, Japanese interest rates remain low. These factors all
portend greater economic activity. In response, we have shifted our investment
focus in Japan to companies that service their domestic market.

PROSPECTING IN LATIN AMERICA. Latin American countries finally are allowing
market forces to push their economies ahead. We are currently focusing on
Mexico.


OUTLOOK
PORTFOLIO MANAGER
DANIEL J. DUANE

DIFFERENT PATHS FOR JAPAN AND EUROPE.

"Japan's legendary high productivity has historically been concentrated in
export-oriented companies, leaving products for the home market quite expensive.
The yen has fallen, but the Japanese -- especially those who have traveled --
have gotten a taste of low-priced consumer items. They are ready to spend
heavily on domestic goods if the prices are right. New government policies will
encourage restructuring of firms that sell to this domestic market. We have seen
the benefits of this process elsewhere, and we expect it to provide good
opportunities for our growth strategy.

"The European domestic markets are likely to be weakened by resistance to more
competitive economic practices. Investors who had been anticipating the benefits
of a single large market and a strong single European currency have been shocked
by the Socialist election victory in France. We will continue to focus on
efficient companies that are not dependent on domestic market growth."

                      NOTES TO THE FINANCIAL STATEMENTS OF
                             CERTAIN PORTFOLIOS OF
                        THE PRUDENTIAL SERIES FUND, INC.
                                  (UNAUDITED)
 
NOTE 1:  GENERAL
 
The Prudential Series Fund, Inc. ('Series Fund'), a Maryland corporation,
organized on November 15, 1982, is a diversified open-end management investment
company registered under the Investment Company Act of 1940, as amended. The
Series Fund is composed of fifteen Portfolios ('Portfolio' or 'Portfolios'),
each with a separate series of capital stock. The information presented in these
financial statements pertains to only the eight Portfolios available for
investment by Discovery Select: Money Market Portfolio, Diversified Bond
Portfolio, High Yield Bond Portfolio, Stock Index Portfolio, Equity Income
Portfolio, Equity Portfolio, Prudential Jennison Portfolio and Global Portfolio.
Shares in the Series Fund are currently sold only to certain separate accounts
of The Prudential Insurance Company of America ('The Prudential'), Pruco Life
Insurance Company and Pruco Life Insurance Company of New Jersey (together
referred to as the 'Companies') to fund benefits under certain variable life
insurance and variable annuity contracts ('contracts') issued by the Companies.
The accounts invest in shares of the Series Fund through subaccounts that
correspond to the portfolios. The accounts will redeem shares of the Series Fund
to the extent necessary to provide benefits under the contracts or for such
other purposes as may be consistent with the contracts.
 
NOTE 2:  ACCOUNTING POLICIES
 
The following is a summary of significant accounting policies consistently
followed by the Series Fund in preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.
 
SECURITIES VALUATION:  Securities traded on an exchange (whether domestic or
foreign) are valued at the last reported sales price on the primary exchange on
which they are traded. Securities traded in the over-the-counter market
(including securities listed on exchanges for which a last sales price is not
available) are valued at the average of the last reported bid and asked prices.
Convertible debt securities are valued at the mean between the most recently
quoted bid and asked prices provided by principal market makers. High yield
bonds are valued either by quotes received from principal market makers or by an
independent pricing service which determine prices by analysis of quality,
coupon, maturity and other factors. Any security for which a reliable market
quotation is unavailable is valued at fair value as determined in good faith by
or under the direction of the Series Fund's Board of Directors.
 
The Money Market Portfolio uses amortized cost to value short-term securities.
Short-term securities that are held in the other Portfolios which mature in more
than 60 days are valued at current market quotations and those short-term
securities which mature in 60 days or less are valued at amortized cost.
 
REPURCHASE AGREEMENTS:  In connection with transactions in repurchase agreements
with U.S. financial institutions, it is the Series Fund's policy that its
custodian or designated subcustodians, as the case may be under triparty
repurchase agreements, take possession of the underlying collateral securities,
the value of which exceeds the principal amount of the repurchase transaction
including accrued interest. If the seller defaults and the value of the
collateral declines or if bankruptcy proceedings are commenced with respect to
the seller of the security, realization of the collateral by the Series Fund may
by delayed or limited. (See Note 5).
 
FOREIGN CURRENCY TRANSLATION:  The books and records of the Series Fund are
maintained in U.S. dollars. Foreign currency amounts are translated into U.S.
dollars on the following basis:
 
(i) market value of investments securities, other assets and liabilities - at
the current rates of exchange.
 
(ii) purchases and sales of investment securities, income and expenses -at the
rate of exchange prevailing on the respective dates of such transactions.
 
Although the net assets of the Series Fund are presented at the foreign exchange
rates and market values at the close of the fiscal period, the Series Fund does
not isolate that portion of the results of operations arising as a result of
changes in the foreign exchange rates from the fluctuations arising from changes
in the market prices of securities held at the end of the period. Similarly, the
Series Fund does not isolate the effect of
 
                                       62
<PAGE>
changes in foreign exchange rates from the fluctuations arising from changes in
the market prices of long-term portfolio securities sold during the period.
Accordingly, these realized foreign currency gains (losses) are included in the
reported net realized gains (losses) on investment transactions.
 
Net realized gains (losses) on foreign currency transactions represent net
foreign exchange gains or losses from holdings of foreign currencies, currency
gains or losses realized between the trade and settlement dates on security
transactions, and the difference between the amounts of dividends, interest and
foreign taxes recorded on the Series Fund's books and the U.S. dollar equivalent
amounts actually received or paid. Net unrealized currency gains or losses from
valuing foreign currency denominated assets and liabilities (other than
investments) at period end exchange rates are reflected as a component of net
unrealized appreciation (depreciation) on investments and foreign currencies.
 
Foreign security and currency transactions may involve certain considerations
and risks not typically associated with those of domestic origin as a result of,
among other factors, the possibility of political and economic instability and
the level of governmental supervision and regulation of foreign securities
markets.
 
SHORT SALES:  Certain portfolios of the Series Fund may sell a security it does
not own in anticipation of a decline in the market value of that security (short
sale). When the Portfolio makes a short sale, it must borrow the security sold
short and deliver it to the broker-dealer through which it made the short sale
as collateral for its obligation to deliver the security upon conclusion of the
sale. The Portfolio may have to pay a fee to borrow the particular security and
may be obligated to remit any interest or dividends received on such borrowed
securities. A gain, limited to the price at which the Portfolio sold the
security short, or a loss, unlimited in magnitude, will be recognized upon the
termination of a short sale if the market price at termination is less than or
greater than, respectively, the proceeds originally received.
 
OPTIONS:  The Series Fund may either purchase or write options in order to hedge
against adverse market movements or fluctuations in value with respect to
securities which the Series Fund currently owns or intends to purchase. The
Series Fund's principal reason for writing options is to realize, through
receipts of premiums, a greater current return than would be realized on the
underlying security alone. When the Series Fund purchases an option, it pays a
premium and an amount equal to that premium is recorded as an investment. When
the Series Fund writes an option, it receives a premium and an amount equal to
that premium is recorded as a liability. The investment or liability is adjusted
daily to reflect the current market value of the option. If an option expires
unexercised, the Series Fund realizes a gain or loss to the extent of the
premium received or paid. If an option is exercised, the premium received or
paid is an adjustment to the proceeds from the sales or the cost of the purchase
in determining whether the Series Fund has realized a gain or loss. The
difference between the premium and the amount received or paid on effecting a
closing purchase or sale transaction is also treated as a realized gain or loss.
Gain or loss on purchased options is included in net realized gain (loss) on
investment transactions. Gain or loss on written options is presented separately
as net realized gain (loss) on written option transactions.
 
The Series Fund, as writer of an option, may have no control over whether the
underlying securities may be sold (called) or purchased (put). As a result, the
Series Fund bears the market risk of an unfavorable change in the price of the
security underlying the written option. The Series Fund, as purchaser of an
option, bears the risk of the potential inability of the counterparties to meet
the terms of their contracts.
 
FINANCIAL FUTURES CONTRACTS:  A financial futures contract is an agreement to
purchase (long) or sell (short) an agreed amount of securities at a set price
for delivery on a future date. Upon entering into a financial futures contract,
the Series Fund is required to pledge to the broker an amount of cash and/or
other assets equal to a certain percentage of the contract amount. This amount
is known as the 'initial margin'. Subsequent payments, known as 'variation
margin', are made or received by the Series Fund each day, depending on the
daily fluctuations in the value of the underlying security. Such variation
margin is recorded for financial statement purposes on a daily basis as
unrealized gain or loss. When the contract expires or is closed, the gain or
loss is realized and is presented in the statement of operations as net realized
gain (loss) on financial futures contracts.
 
The Series Fund invests in financial futures contracts in order to hedge its
existing portfolio securities or securities the Series Fund intends to purchase,
against fluctuations in value. Under a variety of circumstances, the Series Fund
may not achieve the anticipated benefits of the financial futures contracts and
may realize a loss. The use of futures transactions involves the risk of
imperfect correlation in movements in the price of futures contracts and the
underlying assets.
 
                                       63
<PAGE>
SECURITIES TRANSACTIONS AND INVESTMENT INCOME:  Securities transactions are
recorded on the trade date. Realized gains and losses on sales of securities are
calculated on the identified cost basis. Dividend income is recorded on the
ex-dividend date; interest income, which is comprised of three elements: stated
coupon, original issue discount and market discount, is recorded on the accrual
basis. Certain portfolios own shares of real estate investment trusts ('REITs')
which report information on the source of their distributions annually. A
portion of distributions received from REITs during the period is estimated to
be a return of capital and is recorded as a reduction of their costs. Expenses
are recorded on the accrual basis which may require the use of certain estimates
by management. The Series Fund expenses are allocated to the respective
portfolios on the basis of relative net assets.
 
CUSTODY FEE CREDITS:  The Series Fund, exclusive of the Global Portfolio, has an
arrangement with its custodian bank, whereby uninvested monies earn credits
which reduce the fees charged by the custodian. Such custody fee credits are
presented as a reduction of gross expenses in the accompanying Statement of
Operations.
 
TAXES:  For federal income tax purposes, each portfolio in the Series Fund is
treated as a separate taxpaying entity. It is the intent of the Series Fund to
continue to meet the requirements of the Internal Revenue Code applicable to
regulated investment companies and to distribute all of its net income to
shareholders. Therefore, no federal income tax provision is required.
 
Withholding taxes on foreign dividends, interest and capital gains have been
provided for in accordance with the Series Fund's understanding of the
applicable country's tax rules and regulations.
 
DIVIDENDS AND DISTRIBUTIONS:  Dividends and distributions of each Portfolio are
declared in cash and automatically reinvested in additional shares of the Fund.
The Money Market Portfolio will declare and reinvest dividends from net
investment income and net realized capital gain (loss) daily. Each other
Portfolio will declare and distribute dividends from net investment income,if
any, quarterly and net capital gains, if any, at least annually. Dividends and
distributions are recorded on the ex-dividend date.
 
Income distributions and capital gain distributions are determined in accordance
with income tax regulations which may differ from generally accepted accounting
principles.
 
RECLASSIFICATION OF CAPITAL ACCOUNTS:  The Series Fund accounts for and reports
distributions to shareholders in accordance with the American Institute of
Certified Public Accountants' Statement of Position 93-2: Determination,
Disclosure, and Financial Statement Presentation of Income, Capital Gains, and
Return of Capital Distributions by Investment Companies. As a result of this
statement, the Series Fund changed the classification of distributions to
shareholders to disclose the amounts of undistributed net investment income and
accumulated net realized gain (loss) on investments available for distributions
determined in accordance with income tax regulations. For the six months ended
June 30, 1997, the application of this statement increased (decreased) net
unrealized appreciation on investments (APP), paid-in capital in excess of par
(PC), undistributed net investment income ('UNI') and accumulated net realized
gains (losses) on investments ('GL') by the following amounts:
