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 be assuming too much risk by concentrating their investments in just a
handful of stocks or sectors or by "chasing performance."
   Alan Greenspan, the Chairman of the Federal Reserve Board, has stated his
view that the recent spectacular returns of some sectors of the market are
partly responsible for pushing our economy to growth rates that could lead to
higher inflation. The dramatic rise in the prices of a narrow segment of the
market has created enormous wealth for some investors. In turn, those investors
are spending at a rate that the Fed believes may 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 is 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 are clear: investors must 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 could reduce corporate
earnings and put downward pressure on stock prices. Highly valued stocks may be
particularly vulnerable to a correction. The Securities and Exchange Commission
Chairman, Arthur Levitt, has cautioned investors against the expectation that
the types of returns seen in the recent bull market will last forever. We agree.

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 "new economy" stocks have risen since our last report to you, many "old
economy" stocks are selling at unusually 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 in the future. Of course, there
is no assurance that value investing will return to favor in the market, but it
may be a diversification strategy to consider for part of your portfolio.
   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 fluctuation, 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/James C. Swain            /s/Bridget A. Macaskill

AN INTERVIEW WITH YOUR FUND'S MANAGERS


Q How would you characterize the Fund's performance during the six-month period
that ended February 29, 2000?

A. Much like the S&P 500 Index and many of the Fund's peers, Oppenheimer Main
Street Growth & Income Fund made little progress over the recent six-month
period. Despite generally favorable conditions in the economy, the stock market
was characterized by high volatility and enormous disparity among its different
sectors.

What made this such a volatile period?

Throughout the period, investors struggled to weigh the positive impact of
encouraging economic data against the negative impact of rising interest rates.
During the first few months of the period, equity markets were driven higher by
continued strength in the U.S. economy, low rates of inflation, growing evidence
of global economic recovery and diminishing fears of Y2K-related problems. By
the beginning of the new year, most market indices had risen to new all-time
highs.
   However, this favorable investment environment proved short-lived. Concerned
that the U.S. economy's rate of growth could give rise to inflation, the Federal
Reserve Board ("Fed") raised interest rates in February 2000, the fourth such
rate hike in less than a year. Rate hikes tend to hurt the profitability of many
types of corporations by raising the cost of borrowed capital and reducing the
present value of future earnings. Although investors had shrugged off earlier
rate hikes, concerns surrounding the Fed's February action drove many stocks
lower.

AN INTERVIEW WITH YOUR FUND'S MANAGERS


The only sectors that seemed relatively unaffected by such concerns were
technology and biotechnology, both of which rose sharply in January and
February. Despite interest rate concerns, investors seemed willing to pay
increasingly higher prices for the high growth potential of many
technology-related stocks. In February, at the same time the S&P 500 was
falling, the technology-heavy Nasdaq Composite Index was reaching new highs.

How did you manage the Fund in light of these conditions?

Throughout the period we focused primarily on large-cap stocks that included
both value and growth-like names. Based on prevailing market conditions during
the period, our quantitative cap-size models forecasted the continued superior
performance of the largest-capitalization stocks, while discouraging investment
in "deep value" and speculative growth categories.
   We achieved strong performance from investments in broadly diverse sectors of
the economy. Many of our energy holdings benefited from steadily rising prices
for oil and gas, and consolidations among several of the industry's key players.
Our consumer cyclical stocks were aided by strong consumer spending. Our
telecommunications holdings advanced amid growing business demand for voice and
data communications services. Our biotechnology stocks showed strong gains as
established companies profited from a growing roster of new drugs with
blockbuster potential.
   The Fund also shared in the powerful growth of the technology sector. We
concentrated our technology holdings among the larger and better established
companies, while limiting exposure to newer, highly speculative companies.



[CALLOUT]
"We continually refine our investment process, emphasizing factors we believe
are most likely to predict market performance."

<PAGE>


As the rally in technology drove the value of some stocks to levels we
considered unsustainable, we trimmed some of our holdings. However, we continued
to hold a sizeable, though slightly reduced, position in the sector.

Did any of the Fund's investments fail to meet your expectations?

In general, value-oriented stocks continued their pattern of underperformance
throughout the period. However, we believe that such holdings will serve the
Fund's shareholders well in the event of a shift in market sentiment in favor of
value.
   The Fund's performance also suffered as a result of problems within certain
industry sectors. Our holdings among non-biotech healthcare stocks were hurt by
regulatory challenges and diminishing patent protection for established
pharmaceuticals. Our financial industry holdings were pressured by the rising
interest rate environment, which tends to have a disproportionately negative
impact on financial services stocks.

What is your outlook for the coming months?

Currently, our quantitative cap-size model suggests improving prospects for mid-
and small-cap stocks in the coming months. Additional models favor a balance of
growth and value factors in determining the stocks best able to weather market
conditions and participate in market strength. Of course, our models constantly
evolve in response not only to changing stock data, but also to changing market
dynamics.

NOTES TO FINANCIAL STATEMENTS   Unaudited


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

 Oppenheimer Main Street Growth & Income Fund (the Fund) is a separate series of
 Oppenheimer Main Street Funds, Inc., an open-end management investment company
 registered under the Investment Company Act of 1940, as amended. The Fund's
 invest-ment objective is to seek a high total return, which includes current
 income and capital appreciation in the value of its shares, from equity and
 debt securities. The Fund's investment advisor is OppenheimerFunds, Inc. (the
 Manager).
    The Fund offers Class A, Class B, Class C and Class Y 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).
 Class Y shares are sold to certain institutional investors without either a
 front-end sales charge or a 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. No such plan has been adopted for
 Class Y shares. 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.
- --------------------------------------------------------------------------------
 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.


34 | OPPENHEIMER MAIN STREET GROWTH & INCOME FUND
<PAGE>

- --------------------------------------------------------------------------------
 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.
- --------------------------------------------------------------------------------
 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

 4. Fees and Other Transactions with Affiliates  Continued

 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
 February 29, 2000, payments under the Class A plan totaled $9,826,268, all of
 which was paid by the Distributor to recipients. That included $539,244 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.
    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 February 29,
 2000, were as follows:

 5. Foreign Currency Contracts

 A foreign currency contract is a commitment to purchase or sell a foreign
 currency at a future date, at a negotiated rate. The Fund may enter into
 foreign currency contracts for operational purposes and to seek to protect
 against adverse exchange rate fluctuations. Risks to the Fund include the
 potential inability of the counterparty to meet the terms of the contract.
    The net U.S. dollar value of foreign currency underlying all contractual
 commitments held by the Fund and the resulting unrealized appreciation or
 depreciation are determined using foreign currency exchange rates as provided
 by a reliable bank, dealer or pricing service. Unrealized appreciation and
 depreciation on foreign currency contracts are reported in the Statement of
 Assets and Liabilities.
    The Fund may realize a gain or loss upon the closing or settlement of the
 foreign currency transactions. Realized gains and losses are reported with all
 other foreign currency gains and losses in the Statement of Operations.
    Securities denominated in foreign currency to cover net exposure on
 outstanding foreign currency contracts are noted in the Statement of
 Investments where applicable.

 As of February 29, 2000, the Fund had outstanding foreign currency contracts as
 follows:

 6. Illiquid or Restricted Securities

 As of February 29, 2000, investments in securities included issues that are
 illiquid or restricted. Restricted securities are often purchased in private
 placement transactions, are not registered under the Securities Act of 1933,
 may have contractual restrictions on resale, and are valued under methods
 approved by the Board of Directors as reflecting fair value. A security may
 also 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 or restricted securities. Certain
 restricted securities, eligible for resale to qualified institutional
 investors, are not subject to that limitation. The aggregate value of illiquid
 or restricted securities subject to this limitation as of February 29, 2000,
 was $22,970,160, which represents 0.13% of the Fund's net assets all of which
 is considered restricted. Information concerning restricted securities is as
 follows:

 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 February
 29, 2000.
