PRESIDENT'S LETTER

Dear Shareholder,

For many years, we have encouraged investors to consider whether they could
tolerate more risk in their long-term investments by participating in the stock
market, which has historically provided higher long-term returns than any other
asset class. Today, however, we have a very different concern: some investors
may have assumed too much risk by concentrating their investments in just a
handful of stocks or sectors or by "chasing performance."

   Several months ago, Alan Greenspan, the Chairman of the Federal Reserve
Board, stated his view that the spectacular returns some sectors of the market
were then experiencing may have been partly responsible for pushing our economy
to growth rates that could lead to higher inflation. Today it is clear that the
dramatic rise in the prices of a narrow segment of the market created enormous
wealth for some investors. The result of this newfound wealth has been a
substantial increase in spending that the Federal Reserve Board believes could
threaten the healthy growth of our economy.

   That's why the Fed has been raising interest rates steadily and decisively
over the past year. By making borrowing more expensive, the Fed has been
attempting to slow economic growth. It is a precarious balancing act: too much
tightening creates the risk of recession, while too little opens the door to
inflation.

   The implications of the Fed's resolve are clear: investors must continue to
be prepared for near-term market volatility. In the bond market, higher interest
rates usually lead to lower bond prices. In the stock market, slower economic
growth often reduces corporate earnings and puts downward pressure on stock
prices. Highly valued stocks can be particularly vulnerable to a correction. The
Securities and Exchange Commission Chairman, Arthur Levitt, has been cautioning
investors against the expectation that the types of returns seen in the recent
bull market will last forever.

PRESIDENT'S LETTER

   Because of the prospect of continued market volatility, we encourage you to
consider diversifying your investments. Indeed, diversification may help you
mitigate the effects of sharp declines in any one area. It may also help you
better position your portfolio to seek greater returns over the long run.

   While some "new economy" stocks have risen over the last year, many so-called
"old economy" stocks are selling at low prices. In the bond market, higher
interest rates over the short term may reduce inflation concerns, which should
be beneficial over the long term. By buying out-of-favor investments, you may be
able to profit when and if they return to favor.

   What specific investments should you consider today so that you are prepared
for tomorrow? The answer depends on your individual investing goals, risk
tolerance and financial circumstances. We urge you to talk with your financial
advisor about ways to diversify your portfolio. This may include considering
global diversification as part of your strategy. While investing abroad has
special risks, such as the effects of foreign currency fluctuations, it also
offers opportunities to participate in global economic growth and to hedge
against the volatility in U.S. markets.

   We thank you for your continued confidence in OppenheimerFunds, The Right Way
to Invest.

Sincerely,

/s/ Bridget A. Macaskill

AN INTERVIEW WITH YOUR FUND'S MANAGERS

Q. How would you characterize the Fund's performance during the six months that
ended April 30, 2000?

A. This was a challenging period for both stock and bond investing, especially
among the value-oriented equities on which the Fund focuses its equity
investments. However, our disciplined strategy of allocating assets among
stocks, bonds and cash enabled us to limit risks and improve returns for our
shareholders.

Why has this been such a challenging period for the Fund's stock performance?

Historically, value stocks have proven to be bargains over the long term. How
ever, they tend to underperform the market when corporate earnings growth
appears likely to slow and concerns regarding the economic future are on the
rise. At such times, investors tend to seek large, growth-oriented companies.

   Throughout the recent six-month period, actual U.S. economic growth remained
robust. However, the unusually rapid pace of U.S. economic growth raised
concerns that inflation might appear. In an effort to prevent the economy from
overheating, the Federal Reserve Board (the Fed) raised interest rates, and
declared that they intended to continue raising them until the pace of consumer
spending and economic growth slowed. The Fed's actions and statements heightened
uncertainties regarding the sustainability of U.S. economic growth, and
value-oriented stocks suffered as a result. Many of our holdings in traditional
value-oriented sectors were hard hit despite good earnings and strong business
conditions.

How did you allocate the Fund's assets in light of these conditions?

We conduct in-depth analyses of financial markets and economic trends to guide
our decisions on allocating the Fund's assets among stocks, bonds and cash.
During the recent period, our analyses led us to invest approximately 40% of the
Fund's

AN INTERVIEW WITH YOUR FUND'S MANAGERS

assets in bonds and cash. These investments enhanced the Fund's performance in
an environment that was generally unfavorable for value-oriented stocks.

What actions did you take to enhance the performance of the Fund's stocks?

We believe we positioned the Fund's equity holdings to perform as strongly as
possible during a difficult time for value investing. During the period, we
added substantially to our value-oriented technology holdings to take advantage
of strength in the computer and telecommunications industries. The percentage of
the Fund's assets allocated to technology rose from approximately 10% of the
Fund's stocks at the beginning of the period to approximately 20% near the end
of the period.1 Most of the Fund's best performing stocks were concentrated in
this sector. We also scored successes with several of our energy holdings, which
benefited from a rebound in energy prices, and certain utility holdings, which
participated in the explosive build-out of cellular and fiber-optic
communications networks.

   While these moves enhanced the Fund's performance, the negative environment
for value investing still took a significant toll. Stocks in the consumer
staples sector, including beverage companies and other commodity suppliers, lost
value in spite of strong company fundamentals and good earnings performance.
Solid companies in the capital goods sector faced a similarly unfavorable
investment environment. Reasonably priced stocks of retailers in the consumer
cyclical sector also turned in disappointing performance as investors focused on
a narrow group of high growth companies in the sector.

How did you manage the Fund's bond exposure?

We invested a relatively high percentage of the Fund's bond portfolio in
long-term Treasury bonds. This proved to be an effective portfolio management
strategy. Due to supply and demand factors driven by a Treasury Department
buyback of long-term bonds, these investments outperformed most other sectors of
the bond market.


"We added substantially to our
value-oriented technology holdings to take
advantage of strength in the computer
and telecommunications industries."

   Corporate bonds, on the other hand, came under pricing pressures as a result
of rising interest rates and an oversupply of corporate debt issuance. We took
advantage of the relatively low prices of high-quality corporate bonds during
the period, opportunistically increasing the Fund's exposure to
high-credit-rated corporate bonds.

What is your outlook for the future in light of today's market conditions?

A gap of unprecedented dimensions has opened between the prices of
value-oriented stocks and growth-oriented stocks. However, the vulnerability of
some overpriced growth stocks was exposed during April 2000, when prices of some
of the market's highest fliers fell significantly. We continue to believe a
balanced portfolio that includes bonds, undervalued stocks and cash offers
investors the potential for attractive long-term total returns. We remain
committed to a disciplined asset allocation and investment strategy designed to
deliver such returns to our investors. That's why Oppenheimer Disciplined
Allocation Fund remains part of The Right Way to Invest.

Footnotes to Statement of Investments

1. Non-income-producing security.
2. Identifies issues considered to be illiquid--See Note 6 of Notes to Financial
Statements.
3. Represents a security sold under Rule 144A, which are exempt from
registration under the Securities Act of 1933, as amended. These securities have
been determined to be liquid under guidelines established by the Board of
Directors. These securities amount to $2,738,867 or 1.52% of the Fund's net
assets as of April 30, 2000.
4. Interest-Only Strips represent the right to receive the monthly interest
payments on an underlying pool of mortgage loans. These securities typically
decline in price as interest rates decline. Most other fixed income securities
increase in price when interest rates decline. The principal amount of the
underlying pool represents the notional amount on which current interest is
calculated. The price of these securities is typically more sensitive to changes
in prepayment rates than traditional mortgage-backed securities (for example,
GNMA pass-throughs). Interest rates disclosed represent current yields based
upon the current cost basis and estimated timing and amount of future cash
flows.
5. Represents the current interest rate for a variable or increasing rate
security.
6. Securities with an aggregate market value of $3,281,420 are held in
collateralized accounts to cover initial margin requirements on open futures
sales contracts. See Note 5 of Notes to Financial Statements.
7. Issuer is in default.

 1. Significant Accounting Policies

 Oppenheimer Disciplined Allocation Fund (the Fund), a series of Oppenheimer
 Series Fund, Inc. (the Company), is registered under the Investment Company Act
 of 1940, as amended, as an open-end management investment company. The Fund's
 investment objective is to seek to maximize total investment return (including
 capital appreciation and income) principally by allocating its assets among
 stocks, corporate bonds, U.S. Government securities and money market
 instruments, according to changing market conditions. The Fund's investment
 advisor is OppenheimerFunds, Inc. (the Manager).

    The Fund offers Class A, Class B and Class C shares. Class A shares are sold
 at their offering price, which is normally net asset value plus an initial
 sales charge. Class B and Class C shares are sold without an initial sales
 charge but may be subject to a contingent deferred sales charge (CDSC). All
 classes of shares have identical rights to earnings, assets and voting
 privileges, except that each class has its own expenses directly attributable
 to that class and exclusive voting rights with respect to matters affecting
 that class. Classes A, B and C shares have separate distribution and/or service
 plans. Class B shares will automatically convert to Class A shares six years
 after the date of purchase. The following is a summary of significant
 accounting policies consistently followed by the Fund.

--------------------------------------------------------------------------------
 Securities Valuation. Securities for which quotations are readily available are
 valued at the last sale price, or if in the absence of a sale, at the last sale
 price on the prior trading day if it is within the spread of the closing bid
 and asked prices, and if not, at the closing bid price. Securities (including
 restricted securities) for which quotations are not readily available are
 valued primarily using dealer-supplied valuations, a portfolio pricing service
 authorized by the Board of Directors, or at their fair value. Fair value is
 determined in good faith under consistently applied procedures under the
 supervision of the Board of Directors. Foreign currency contracts are valued
 based on the closing prices of the forward currency contract rates in the
 London foreign exchange markets on a daily basis as provided by a reliable
 bank, dealer or pricing service. Short-term "money market type" debt securities
 with remaining maturities of sixty days or less are valued at cost (or last
 determined market value) and adjusted for amortization or accretion to maturity
 of any premium or discount.

--------------------------------------------------------------------------------
 Security Credit Risk. The Fund invests in high yield securities, which may be
 subject to a greater degree of credit risk, greater market fluctuations and
 risk of loss of income and principal, and may be more sensitive to economic
 conditions than lower yielding, higher rated fixed income securities. The Fund
 may acquire securities in default, and is not obligated to dispose
 of securities whose issuers subsequently default. As of April 30, 2000,
 securities with an aggregate market value of $100,000, representing 0.06% of
 the Fund's net assets, were in default.



26 OPPENHEIMER DISCIPLINED ALLOCATION FUND

<PAGE>

--------------------------------------------------------------------------------
 Foreign Currency Translation. The accounting records of the Fund are maintained
 in U.S. dollars. Prices of securities denominated in foreign currencies are
 translated into U.S. dollars at the closing rates of exchange. Amounts related
 to the purchase and sale of foreign securities and investment income are
 translated at the rates of exchange prevailing on the respective dates of such
 transactions.

    The effect of changes in foreign currency exchange rates on investments is
 separately identified from the fluctuations arising from changes in market
 values of securities held and reported with all other foreign currency gains
 and losses in the Fund's Statement of Operations.

--------------------------------------------------------------------------------
 Repurchase Agreements. The Fund requires the custodian to take possession, to
 have legally segregated in the Federal Reserve Book Entry System or to have
 segregated within the custodian's vault, all securities held as collateral for
 repurchase agreements. The market value of the underlying securities is
 required to be at least 102% of the resale price at the time of purchase. If
 the seller of the agreement defaults and the value of the collateral declines,
 or if the seller enters an insolvency proceeding, realization of the value of
 the collateral by the Fund may be delayed or limited.

--------------------------------------------------------------------------------
 Allocation of Income, Expenses, Gains and Losses. Income, expenses (other than
 those attributable to a specific class), gains and losses are allocated daily
 to each class of shares based upon the relative proportion of net assets
 represented by such class. Operating expenses directly attributable to a
 specific class are charged against the operations of that class.

--------------------------------------------------------------------------------
 Directors' Compensation. The Fund has adopted an unfunded retirement plan for
 the Fund's independent Board of Directors. Benefits are based on years of
 service and fees paid to each director during the years of service. During the
 six months ended April 30, 2000, a provision of $11,473 was made for the Fund's
 projected benefit obligations and payments of $4,206 were made to retired
 directors, resulting in an accumulated liability of $100,410 as of April 30,
 2000.

    The Board of Directors has adopted a deferred compensation plan for
 independent directors that enables directors to elect to defer receipt of all
 or a portion of annual compensation they are entitled to receive from the Fund.
 Under the plan, the compensation deferred is periodically adjusted as though an
 equivalent amount had been invested for the Board of Directors in shares of one
 or more Oppenheimer funds selected by the director. The amount paid to the
 Board of Directors under the plan will be determined based upon the performance
 of the selected funds. Deferral of directors' fees under the plan will not
 affect the net assets of the Fund, and will not materially affect the Fund's
 assets, liabilities or net investment income per share.

================================================================================
 1. Significant Accounting Policies Continued

 Federal Taxes. The Fund intends to continue to comply with provisions of the
 Internal Revenue Code applicable to regulated investment companies and to
 distribute all of its taxable income, including any net realized gain on
 investments not offset by loss carryovers, to shareholders. Therefore, no
 federal income or excise tax provision is required.

--------------------------------------------------------------------------------
 Dividends and Distributions to Shareholders. Dividends and distributions to
 shareholders, which are determined in accordance with income tax regulations,
 are recorded on the ex-dividend date.

--------------------------------------------------------------------------------
 Classification of Distributions to Shareholders. Net investment income (loss)
 and net realized gain (loss) may differ for financial statement and tax
 purposes. The character of distributions made during the year from net
 investment income or net realized gains may differ from its ultimate
 characterization for federal income tax purposes. Also, due to timing of
 dividend distributions, the fiscal year in which amounts are distributed may
 differ from the fiscal year in which the income or realized gain was recorded
 by the Fund.

--------------------------------------------------------------------------------
 Expense Offset Arrangements. Expenses paid indirectly represent a reduction of
 custodian fees for earnings on cash balances maintained by the Fund.

--------------------------------------------------------------------------------
 Other. Investment transactions are accounted for as of trade date and dividend
 income is recorded on the ex-dividend date. Certain dividends from foreign
 securities will be recorded as soon as the Fund is informed of the dividend if
 such information is obtained subsequent to the ex-dividend date. Realized gains
 and losses on investments and unrealized appreciation and depreciation are
 determined on an identified cost basis, which is the same basis used for
 federal income tax purposes.

    The preparation of financial statements in conformity with generally
 accepted accounting principles requires management to make estimates and
 assumptions that affect the reported amounts of assets and liabilities and
 disclosure of contingent assets and liabilities at the date of the financial
 statements and the reported amounts of income and expenses during the reporting
 period. Actual results could differ from those estimates.

</TABLE>

 The Fund has adopted a Service Plan for Class A shares and Distribution and
 Service Plans for Class B and Class C shares under Rule 12b-1 of the Investment
 Company Act. Under those plans the Fund pays the Distributor for all or a
 portion of its costs incurred in connection with the distribution and/or
 servicing of the shares of the particular class.

--------------------------------------------------------------------------------
 Class A Service Plan Fees. Under the Class A service plan, the Distributor
 currently uses the fees it receives from the Fund to pay brokers, dealers and
 other financial institutions. The Class A service plan permits reimbursements
 to the Distributor at a rate of up to 0.25% of average annual net assets of
 Class A shares purchased. The Distributor makes payments to plan recipients
 quarterly at an annual rate not to exceed 0.25% of the average annual net
 assets consisting of Class A shares of the Fund. For the six months ended April
 30, 2000, payments under the Class A plan totaled $235,673, all of which was
 paid by the Distributor to recipients. That included $183,851 paid to an
 affiliate of the Manager. Any unreimbursed expenses the Distributor incurs with
 respect to Class A shares in any fiscal year cannot be recovered in subsequent
 years.

--------------------------------------------------------------------------------
 Class B and Class C Distribution and Service Plan Fees. Under each plan,
 service fees and distribution fees are computed on the average of the net asset
 value of shares in the respective class, determined as of the close of each
 regular business day during the period. The Class B and Class C plans provide
 for the Distributor to be compensated at a flat rate, whether the Distributor's
 distribution expenses are more or less than the amounts paid by the Fund under
 the plan during the period for which the fee is paid.


30 OPPENHEIMER DISCIPLINED ALLOCATION FUND

<PAGE>

    The Distributor retains the asset-based sales charge on Class B shares. The
 Distributor retains the asset-based sales charge on Class C shares during the
 first year the shares are outstanding. The asset-based sales charges on Class B
 and Class C shares allow investors to buy shares without a front-end sales
 charge while allowing the Distributor to compensate dealers that sell those
 shares.

    The Distributor's actual expenses in selling Class B and Class C shares may
 be more than the payments it receives from the contingent deferred sales
 charges collected on redeemed shares and asset-based sales charges from the
 Fund under the plans. If any plan is terminated by the Fund, the Board of
 Directors may allow the Fund to continue payments of the asset-based sales
 charge to the Distributor for distributing shares before the plan was
 terminated. The plans allow for the carry-forward of distribution expenses, to
 be recovered from asset-based sales charges in subsequent fiscal periods.

    Distribution fees paid to the Distributor for the six months ended April 30,
 2000, were as follows:

 5. Futures Contracts

 The Fund may buy and sell futures contracts in order to gain exposure to or to
 seek to protect against changes in interest rates. The Fund may also buy or
 write put or call options on these futures contracts.

    The Fund generally sells futures contracts to hedge against increases in
 interest rates and the resulting negative effect on the value of fixed rate
 portfolio securities. The Fund may also purchase futures contracts to gain
 exposure to changes in interest rates as it may be more efficient or cost
 effective than actually buying fixed income securities.

    Upon entering into a futures contract, the Fund is required to deposit
 either cash or securities (initial margin) in an amount equal to a certain
 percentage of the contract value. Subsequent payments (variation margin) are
 made or received by the Fund each day. The variation margin payments are equal
 to the daily changes in the contract value and are recorded as unrealized gains
 and losses. The Fund may recognize a realized gain or loss when the contract is
 closed or expires.

    Securities held in collateralized accounts to cover initial margin
 requirements on open futures contracts are noted in the Statement of
 Investments. The Statement of Assets and Liabilities reflects a receivable
 and/or payable for the daily mark to market for variation margin.

    Risks of entering into futures contracts (and related options) include the
 possibility that there may be an illiquid market and that a change in the value
 of the contract or option may not correlate with changes in the value of the
 underlying securities.

</TABLE>


================================================================================
 6. Illiquid Securities

 As of April 30, 2000, investments in securities included issues that are
 illiquid. A security may be considered illiquid if it lacks a readily available
 market or if its valuation has not changed for a certain period of time. The
 Fund intends to invest no more than 10% of its net assets (determined at the
 time of purchase and reviewed periodically) in illiquid securities. The
 aggregate value of illiquid securities subject to this limitation as of April
 30, 2000, was $2,485,149, which represents 1.38% of the Fund's net assets.

================================================================================
 7. Bank Borrowings

 The Fund may borrow from a bank for temporary or emergency purposes including,
 without limitation, funding of shareholder redemptions provided asset coverage
 for borrowings exceeds 300%. The Fund has entered into an agreement which
 enables it to participate with other Oppenheimer funds in an unsecured line of
 credit with a bank, which permits borrowings up to $400 million, collectively.
 Interest is charged to each fund, based on its borrowings, at a rate equal to
 the Federal Funds Rate plus 0.45%. Borrowings are payable 30 days after such
 loan is executed. The Fund also pays a commitment fee equal to its pro rata
 share of the average unutilized amount of the credit facility at a rate of
 0.08% per annum.

    The Fund had no borrowings outstanding during the six months ended April 30,
 2000.
