Dear Shareholder:

The six months ended April 30 were a roller-coaster in the markets. The Dow
opened on November 1, 2001 at 9075 and closed on April 30, 2002 at 9946,
while the Nasdaq began at 1690 and closed on April 30, 2002 at 1688. The
Dow recovered from the lows it reached in the aftermath of September 11;
the Nasdaq's performance was less impressive. After a volatile run-up and
an equally volatile decline, especially in the technology sector, we are
now in a narrow trading range, and we expect that to continue for some
time. For the six-month period, the Castle Convertible Fund returned 7.61%,
while the S&P was up 2.31% and the Lehman Brothers Government/Credit Bond
Index was down 1.00%.

The last quarter of 2001 was a difficult one for the economy and for the
country. The economy had already entered a recession in the summer, but the
events of September 11 pushed the markets lower and raised serious concerns
about the future. The first quarter of 2002 showed signs that the recession
was coming to a swift end and that the economic downturn would be far less
severe than some had feared. The recession was largely the result of a halt
in business spending and the need for companies to eliminate excess
inventories. Consumers, who make up two-thirds of America's $10 trillion
economy, continued to spend during this period, with personal consumption
expenditures growing steadily at more than 2.5%. As a result of the
inventory draw-down, tax-cuts, and emergency government spending, the
economy actually grew at an annual rate of 5.6% in the first quarter of
2002, while productivity showed remarkable gains of 8.46%, in part due to
increased efficiency brought about by the widespread integration of
information technologies.

The Federal Reserve, after a dramatic series of rate cuts in the fall of
2001 that brought the Fed Funds rate to 1.75%, adopted a neutral stance,
and rates stayed unchanged in the first months of 2002. We do not expect
that this will change until the end of the year, at the earliest, and even
then, we expect the tightening to be modest. Government fiscal policy for
2002 and beyond will provide some economic stimulus even as rates remain
low. The 10-year note has also been stuck in a low-yield range, fluctuating
only marginally at around 5.00%. The bond market, much like the stock
market, has been in a narrow range, reflecting continued unease on Wall
Street and uncertainty about the political and economic future.

The concerns of Wall Street notwithstanding, going forward, the macro-
economic outlook is positive. The overwhelming majority of economic data
suggests that the economy is growing at a rate of about 3% a year. The
equity markets and Wall Street in general however, have been marching to
the beat of a different drummer and focusing instead on the negatives.
While Wall Street mentality and economic reality may diverge for a while,
corporate America has become more efficient and more productive and the
overall economy is healthy; sooner rather than later, both financial
markets will reflect that fact. This is a challenging period, no doubt, but
many companies have become more efficient as a result. We will continue to
identify such companies, and we anticipate that they will yield strong
results in the months ahead.

                                       Respectfully submitted,

                                       /s/ Dan C. Chung

CASTLE CONVERTIBLE FUND, INC.
NOTES TO FINANCIAL STATEMENTS (Unaudited)

NOTE 1-Summary of Significant Accounting Policies:

      Castle Convertible Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940, as a diversified, closed-end management
investment company. The Fund's investment adviser is Fred Alger Management,
Inc. (the "Adviser").

      The following is a summary of significant accounting policies
consistently followed by the Fund in the preparation of its financial
statements.

(a) Investment Valuation-Investments in securities are valued at 4:00 p.m.
Eastern time. Listed and unlisted securities for which such information is
regularly reported are valued at the last reported sales price or, in the
absence of reported sales, at the mean between the bid and asked price or,
in the absence of a recent bid or asked price, the equivalent as obtained
from one or more of the major market makers for the securities to be
valued. Securities for which market quotations are not readily available
are valued at fair value, as determined in good faith pursuant to
procedures established by the Board of Directors. Short-term investments
are valued at amortized cost which approximates market value.

(b) Securities Transactions and Investment Income-Securities transactions
are recorded on a trade date basis. Realized gains and losses from
securities transactions are recorded on the basis of the first-in, first-
out method. Dividend income is recognized on the ex-dividend date and
interest income is recognized on the accrual basis.

      Effective November 1, 2001, premiums and discounts on debt securities
purchased are amortized or accreted over the lives of the respective
securities. This change in accounting policy which has been applied
retroactively had no material effect on the accompanying financial
statements.

(c) Dividends to Shareholders-Dividends payable to shareholders are
recorded by the Fund on the ex-dividend date. Dividends from net investment
income are declared and paid quarterly. Distributions from net realized
gains are declared and paid annually after the end of the fiscal year in
which earned.

(d) Federal Income Taxes-It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated
investment companies and to distribute all of its taxable income, including
net realized capital gains, to its shareholders. Therefore, no federal
income tax provision is required. At October 31, 2001, the net capital loss
carryforward of the Fund which may be used to offset future net realized
gains was approximately $119,000, and expires in 2009.

(e) Other-These financial statements have been prepared using estimates and
assumptions that affect the reported amounts therein. Actual results may
differ from those estimates.

NOTE 2-Investment Advisory Fees and Other Transactions with Affiliates:

(a) Investment Advisory Fees-Fees incurred by the Fund, pursuant to the
provisions of an Investment Advisory Contract (the "Contract") with the
Adviser, are payable monthly and computed at an annual rate of .75% based
on the Fund's average weekly net asset value.

      The Contract further provides that if in any fiscal year the
aggregate expenses of the Fund (excluding interest, brokerage commissions,
taxes and extraordinary expenses) should exceed 1.5% of the first $30
million of average net assets and 1.0% of the average net assets of the
Fund over $30 million, the Adviser will reimburse the Fund for such excess
expenses. For the six months ended April 30, 2002, no reimbursement was
required pursuant to the Contract. For the six months ended April 30, 2002,
the total investment advisory fee charged to the Fund amounted to $220,893,
and the Adviser received $9,000 for bookkeeping services supplied to the
Fund at cost.

(b) Transfer Agent Fees-Alger Shareholder Services, Inc. ("Alger
Services"), an affiliate of the Adviser, serves as transfer agent for the
Fund. During the six months ended April 30, 2002, the Fund incurred fees of
approximately $7,000 for services provided by Alger Services and reimbursed
Alger Services approximately $2,000 for transfer agent related expenses
paid by Alger Services on behalf of the Fund.

(c) Directors' Fees-Certain directors and officers of the Fund are
directors and officers of the Adviser and Alger Services. The Fund pays
each director who is not affiliated with the Adviser or its affiliates an
annual fee of $8,000, payable quarterly, which is reduced proportionately
by any meetings not attended during the quarter.

(d) Other Transactions With Affiliates-At April 30, 2002, the Adviser and
its affiliates owned 451,116 shares of the Fund.

NOTE 3-Securities Transactions:

      During the six months ended April 30, 2002, purchases and sales of
investment securities, excluding short-term securities, aggregated
$50,748,586 and $51,717,179, respectively.

NOTE 4-Components of Net Assets:

      At April 30, 2002, the Fund's net assets consisted of:

                            ========================
</TABLE>

      As of April 30, 2002 the components of distributable earnings on a
tax basis were as follows:

<TABLE>

<s>                                       <c>
Undistributed ordinary income             $  521,674
Undistributed long-term gain                 741,221
Capital loss carrryforward                         -
Unrealized appreciation (depreciation)     5,252,352
</TABLE>

      The difference between book basis and tax-basis undistributed long-
term gain is attributable primarily to the tax deferral of losses on wash
