DEAR SHAREHOLDER

The investment environment was challenging for Merrill Lynch World Income Fund,
Inc. during the quarter ended June 30, 1998. US high-yield bonds--which
accounted for 45% of the Fund's net assets at June quarter end--underperformed
the US Treasury and equity markets. At the same time, emerging markets, the
Fund's other major sector allocation, underperformed more established markets as
difficulties in Asia and Russia spread to other parts of the world.

Despite these difficulties, we believe that there are compelling reasons for
maintaining the Fund's current investment strategy, as detailed in the
discussion of the Fund's investment review. First, we believe that the US
high-yield market continues to offer attractive value. Second, in our view,
there is value also in the emerging markets sector. The portfolio's sector
allocation at June 30, 1998 and the previous quarter are compared below:

However, as a result of the difficult investment environment, our investments in
each of the sectors at June 30, 1998 were: emerging markets securities, 44% of
net assets; US high-yield bonds, 45%; convertible securities, 7%; and global
high-grade bonds, 4%.

Investment Overview

Emerging Markets Sector

Following a rally that propelled yields on emerging markets debt to tighten
approximately 150 basis points (1.50%) relative to US Treasury securities from
mid-January 1998 to mid-May 1998, emerging market spreads were negatively
impacted and reversed that tightening entirely from mid-May 1998 to mid-June
1998. A variety of factors negatively impacted the market: the Indonesian
crisis; South Korean labor unrest; the Japanese and Asian weakness in economic
growth, currencies and banks, especially the possibility of currency
devaluations in The People's Republic of China and Hong Kong; low world
commodity prices; and a crisis of confidence in Russia. As of June 30, 1998, US
dollar-denominated bonds of emerging-markets issuers were trading at yields
3%-5% in excess of the yields on US high-yield bonds of similar credit quality.

Russia and Brazil, which seem to be the most exposed countries to Asian
contagion, became once again the focus of investors. Brazil, which currently
enjoys an almost record-high level of international reserves, continues to see
improvements in its external sector, but is facing some fiscal pressures in an
electoral year. The government has scheduled the bulk of its aggressive
privatization calendar, including its flagship telecommunications company
Telebras, in the third quarter of 1998, which will provide greater support to
Brazil's international reserves and fiscal accounts. Current electoral polls
indicate that a re-election of President Cardoso in the first round is possible
in October. It is too early to speculate on what measures would be implemented
if President Cardoso were re-elected, especially on the fiscal front, to
continue strengthening the Real Plan.

In Russia, on the other hand, investors' uncertainties increased over the
adequacy of foreign reserves as compared to the amount of debt held by foreign
investors. An aggressive fiscal effort was announced and Group of Seven
Industrialized Countries (G-7) and multinational organizations became heavily
involved in advising the Russian government on alternatives to defend its
economic program. In July, after the closing of the quarter, a multi-billion
International Monetary Fund (IMF) and G-7 financial rescue package was enacted.
After a brief interlude, domestic market weakness and capital flight resumed in
the face of unfinished fiscal legislation, deterioration in Russia's domestic
banking sector, renewed Japanese yen weakness and the sharp correction in the US
equity markets. In order to protect its foreign currency reserves, Russian
authorities decreed on August 17, 1998 a widening of the Russian ruble band and
forced restructuring of its local currency debt.

Venezuela, a country which is a large oil producer, has seen its fiscal accounts
impacted by lower international oil prices and political concerns going into
regional and presidential elections toward the end of 1998. The government is
attempting to move forward in their privatization efforts and in passing
legislature to improve the fiscal accounts.

Ecuador and Colombia have recently elected candidates who intend to tighten
fiscal accounts. In the former case, recent fiscal performance has started to
improve markedly over last year, even before the new president is inaugurated.

There is considerable debate currently about the extent of the weakness in Asia
and its effects on the US economy and the rest of the world. The investment
community is focused on the new Japanese government's actions to revitalize its
economy and re-capitalize its banking sector. South Korea, which earlier this
year took decisive steps in that direction as part of their agreement with the
IMF and international banks, is already seeing some results, but the overall
strength of the area appears to hinge on future developments in Japan, given the
relative size of its economy.

We have adopted a cautious view in emerging market bonds, where yield spreads
relative to US Treasury bonds appear generous, but risks need to be monitored
very closely. We remain vigilant of developments in G-7 markets, of fiscal and
foreign exchange reforms in Russia, and of contagion risks in Latin America.

US High-Yield Sector

Buffeted by turmoil in the emerging markets sector, fixed-income investors fled
to the safety of Treasury securities during the June quarter. At the same time,
the US high-yield market began to have difficulty digesting the *heavy new-issue
supply, as inflows into high-yield mutual funds tapered off. During the quarter
ended June 30, 1998, new-issue supply totaled near $97 billion compared to $42
billion for the year-earlier period, a continuing acceleration in new-issue
volume that has led to a near doubling of the high-yield market since 1993.
However, offsetting the heavy supply to some extent has been a heavy pace of
debt retirement, largely a result of merger and acquisition activity. For the
six months ended June 30, 1998, $18 billion of high-yield issues have been
retired at a premium over par value of 8%.

Although changes in investor sentiment and an ample supply of new issues may
lead to a choppy market, we believe that current spreads offer a reasonable risk
premium for high-yield bonds relative to US Treasury securities and represent a
good investment value. Fundamentals for the high-yield market have remained
favorable. In recent years, many companies have acted to shore up balance sheets
through debt repayment and equity issuance and are now better able to withstand
an earnings shortfall. Merger and acquisition activity has been supporting
valuations and cash continues to enter the high-yield market, providing an
ongoing level of demand that tends to support prices.

Throughout the June quarter, our strategy in the high-yield sector of the Fund
was to maintain an above-average credit quality profile. A credit rating of BB
and above made up 58.6% of this sector's assets, compared to a market weighting
of approximately 34%. During the quarter, we reduced our BB-rated positions
through the sale of US Gypsum, Reliance Group Holdings, Inc., VikingStar
Shipping and TCI Communications preferred stock, all at yield spreads of less
than 2% compared to Treasury securities of similar maturity. Coleman Escrow
Corp. and Host Marriott Corporation were tendered at 1% spreads because mergers
and acquisitions activity required that the bonds be retired.

Convertible Securities Sector

After a somewhat overheated start to the year, the convertible market has
recently cooled off. New-issue activity, which is currently slowing, remains on
track in 1998 for a record number of new issues and record amount of capital
raised. However, investors have become more selective, with fewer new offerings
going to smaller price premiums compared to those of late 1997 and early 1998,
when most new issues traded up significantly in the aftermarket. In fact, some
issues have recently traded to immediate discounts to their offering prices,
notwithstanding more generous terms.

During the June quarter, conversion premiums on existing issues experienced some
compression, which resulted from a mild widening of credit quality spreads,
greater supply and the general satiation of demand from convertible investors.
The stock market made little progress over the past three months, its advance
becoming more narrow and selective. The market's breadth statistics (advance/
decline lines and new high/new low indicators) were generally weak and have thus
far failed to confirm new highs in some of the major equity indexes. This poor
breadth is a typical late-cycle bull market phenomenon, and unless the breadth
indicators improve and confirm these new highs, it may signal a corrective phase
for equity prices later this year. Given

these poor internal technical conditions, combined with high valuations on
equities and a general slowing in earnings growth, we will maintain a somewhat
cautious view toward the stock market over the next several quarters.

Throughout the June quarter, we made some significant changes in the Fund's
convertible holdings. Specifically, we found value in the oil sector by taking
advantage of the recent weakness in oil prices, and added the convertible
preferred shares of Chesapeake Energy Corporation and Lomak Petroleum Inc.,
convertible debentures, both of which are oil and gas exploration and
development companies. Other energy-related purchases included Halter Marine
Group, Inc., which constructs vessels that service the offshore oil drilling
industry, and Parker Drilling Company, a worldwide provider of oil and gas
drilling services. We also added to our position in Loews Corp. convertible into
Diamond Offshore Drilling, Inc., another offshore oil and gas drilling company.
In addition, we added the 4% convertibles of Thermo Instrument Systems, Inc., a
manufacturer of analytical instruments, to our existing position in the 4.5%
notes. Further, we added a second tranche to an existing position of Assisted
Living Concepts, Inc., a company that provides personal care and support for the
elderly.

Other significant purchases during the quarter included Kellstrom Industries,
Inc., which manufactures, services and refurbishes aircraft jet engines, and
Owens-Illinois, Inc., an international diversified manufacturer of packaging
products. We took profits in Alza Corp., a pharmaceuticals manufacturer, Apple
Computer, Inc., and Buffets, Inc., a buffet style restaurant chain (through our
holdings in the Hometown Buffets 7% notes). We partially liquidated and took
profits in the convertibles of Office Depot, Inc., an office products retailer.
Our holdings in U.S. Office Products Co., another office products retailer, were
profitably tendered into an exchange offer upon a reorganization of the company.
We profitably liquidated an arbitrage position in Premiere Technologies, Inc., a
company which provides communication services, as gains from short stock
proceeds exceeded losses on the decline in the convertibles. Finally, we sold
our positions in MedPartners, Inc., a physician practice management company,
because of a deterioration in the company's fundamentals.

In Conclusion

We thank you for your continued investment in Merrill Lynch World Income Fund,
Inc., and we look forward to reviewing our outlook and strategy with you again
in our next report to shareholders.

PERFORMANCE DATA

About Fund
Performance

Investors are able to purchase shares of the Fund through the Merrill Lynch
Select Pricing(SM) System, which offers four pricing alternatives:

o     Class A Shares incur a maximum initial sales charge (front-end load) of 4%
      and bear no ongoing distribution or account maintenance fees. Class A
      Shares are available only to eligible investors.

o     Class B Shares are subject to a maximum contingent deferred sales charge
      of 4% if redeemed during the first year, decreasing 1% each year
      thereafter to 0% after the fourth year. In addition, Class B Shares are
      subject to a distribution fee of 0.50% and an account maintenance fee of
      0.25%. These shares automatically convert to Class D Shares after
      approximately 10 years. (There is no initial sales charge for automatic
      share conversions.)

o     Class C Shares are subject to a distribution fee of 0.55% and an account
      maintenance fee of 0.25%. In addition, Class C Shares are subject to a 1%
      contingent deferred sales charge if redeemed within one year of purchase.

o     Class D Shares incur a maximum initial sales charge of 4% and an account
      maintenance fee of 0.25% (but no distribution fee).

None of the past results shown should be considered a representation of future
performance. Figures shown in the "Recent Performance Results" and "Average
Annual Total Return" tables assume reinvestment of all dividends and capital
gains distributions at net asset value on the payable date. Investment return
and principal value of shares will fluctuate so that shares, when redeemed, may
be worth more or less than their original cost. Dividends paid to each class of
shares will vary because of the different levels of account maintenance,
distribution and transfer agency fees applicable to each class, which are
deducted from the income available to be paid to shareholders.

NOTES TO FINANCIAL STATEMENTS

1. Significant Accounting Policies:

Merrill Lynch World Income Fund, Inc. (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, open-end management
investment company. These unaudited financial statements reflect all adjustments
which are, in the opinion of management, necessary to a fair statement of the
results for the interim period presented. All such adjustments are of a normal
recurring nature. The Fund offers four classes of shares under the Merrill Lynch
Select Pricing(SM) System. Shares of Class A and Class D are sold with a
front-end sales charge. Shares of Class B and Class C may be subject to a
contingent deferred sales charge. All classes of shares have identical voting,
dividend, liquidation and other rights and the same terms and conditions, except
that Class B, Class C and Class D Shares bear certain expenses related to the
account maintenance of such shares, and Class B and Class C Shares also bear
certain expenses related to the distribution of such shares. Each class has
exclusive voting rights with respect to matters relating to its account
maintenance and distribution expenditures. The following is a summary of
significant accounting policies followed by the Fund.

(a) Valuation of investments--Portfolio securities which are traded on stock
exchanges are valued at the last sale price on the exchange on which such
securities are traded, as of the close of business on the day the securities are
being valued or, lacking any sales, at the last available bid price. Securities
traded in the over-the-counter market are valued at the last available bid price
prior to the time of valuation. In cases where securities are traded on more
than one exchange, the securities are valued on the exchange designated by or
under the authority of the Board of Directors as the primary market. Securities
which are traded both in the over-the-counter market and on a stock exchange are
valued according to the broadest and most representative market. Options written
are valued at the last sale price in the case of exchange-traded options or, in
the case of options traded in the over-the-counter market, the last asked price.
Options purchased are valued at the last sale price in the case of
exchange-traded options or, in the case of options traded in the
over-the-counter market, the last bid price. Short-term securities are valued at
amortized cost, which approximates market value. Other investments, including
futures contracts and related options, are stated at market value. Securities
and assets for which market quotations are not available are valued at fair
value as determined in good faith by or under the direction of the Fund's Board
of Directors.

                            Merrill Lynch World Income Fund, Inc., June 30, 1998

NOTES TO FINANCIAL STATEMENTS (continued)

(b) Repurchase agreements--The Fund invests in securities pursuant to repurchase
agreements. Under such agreements, the counterparty agrees to repurchase the
security at a mutually agreed upon time and price. The Fund takes possession of
the underlying securities, marks to market such securities and, if necessary,
receives additional securities daily to ensure that the contract is fully
collateralized.

(c) Derivative financial instruments--The Fund may engage in various portfolio
strategies to seek to increase its return by hedging its portfolio against
adverse movements in the equity, debt and currency markets. Losses may arise due
to changes in the value of the contract or if the counterparty does not perform
under the contract.

o Financial futures contracts--The Fund may purchase or sell financial futures
contracts and options on such futures contracts for the purpose of hedging the
market risk on existing securities or the intended purchase of securities.
Futures contracts are contracts for delayed delivery of securities at a specific
future date and at a specific price or yield. Upon entering into a contract, the
Fund deposits and maintains as collateral such initial margin as required by the
exchange on which the transaction is effected. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in value of the contract. Such receipts or payments are known
as variation margin and are recorded by the Fund as unrealized gains or losses.
When the contract is closed, the Fund records a realized gain or loss equal to
the difference between the value of the contract at the time it was opened and
the value at the time it was closed.

o Foreign currency options and futures--The Fund may also purchase or sell
listed or over-the-counter foreign currency options, foreign currency futures
and related options on foreign currency futures as a short or long hedge against
possible variations in foreign exchange rates. Such transactions may be effected
with respect to hedges on non-US dollar denominated securities owned by the
Fund, sold by the Fund but not yet delivered, or committed or anticipated to be
purchased by the Fund.

o Forward foreign exchange contracts--The Fund is authorized to enter into
forward foreign exchange contracts as a hedge against either specific
transactions or portfolio positions. Such contracts are not entered on the
Fund's records. However, the effect on operations is recorded from the date the
Fund enters into such contracts. Premium or discount is amortized over the life
of the contracts.

o Options--The Fund is authorized to write and purchase call and put options.
When the Fund writes an option, an amount equal to the premium received by the
Fund is reflected as an asset and an equivalent liability. The amount of the
liability is subsequently marked to market to reflect the current market value
of the option written. When a security is purchased or sold through an exercise
of an option, the related premium paid (or received) is added to (or deducted
from) the basis of the security acquired or deducted from (or added to) the
proceeds of the security sold. When an option expires (or the Fund enters into a
closing transaction), the Fund realizes a gain or loss on the option to the
extent of the premiums received or paid (or gain or loss to the extent the cost
of the closing transaction exceeds the premium paid or received).

Written and purchased options are non-income producing investments.

(d) Foreign currency transactions--Transactions denominated in foreign
currencies are recorded at the exchange rate prevailing when recognized. Assets
and liabilities denominated in foreign currencies are valued at the exchange
rate at the end of the period. Foreign currency transactions are the result of
settling (realized) or valuing (unrealized) assets or liabilities expressed in
foreign currencies into US dollars. Realized and unrealized gains or losses from
investments include the effects of foreign exchange rates on investments.

(e) 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 to its shareholders. Therefore, no Federal
income tax provision is required. Under the applicable foreign tax law, a
withholding tax may be imposed on interest, dividends, and capital gains at
various rates.

(f) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Dividend income is recorded on the ex-dividend dates. Dividends from foreign
securities where the ex-dividend date may have passed are subsequently recorded
when the Fund has determined the ex-dividend date. Interest income (including
amortization of discount) is recognized on the accrual basis. Realized gains and
losses on security transactions are determined on the identified cost basis.

(g) Prepaid registration fees--Prepaid registration fees are charged to expense
as the related shares are issued.

(h) Dividends and distributions--Dividends from net investment income, excluding
transaction gains/losses, are declared daily and paid monthly. Distributions of
capital gains are recorded on the ex-dividend dates.

(i) Short sales--When the Fund engages in a short sale, an amount equal to the
proceeds received by the Fund is reflected as an asset and equivalent liability.
The amount of the liability is subsequently marked to market to reflect the
market value of the short sale. The Fund maintains a segregated account of
securities as collateral for the short sales. The Fund is exposed to market risk
based on the amount, if any, that the market value of the stock exceeds the
proceeds received.

2. Investment Advisory Agreement and Transactions with Affiliates:

The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services, Inc.
("PSI"), an indirect wholly-owned subsidiary of Merrill Lynch & Co., Inc. ("ML &
Co."), which is the limited partner. The Fund has also entered into a
Distribution Agreement and Distribution Plans with Merrill Lynch Funds
Distributor ("MLFD" or "Distributor"), a division of Princeton Funds
Distributor, Inc. ("PFD"), which is a wholly-owned subsidiary of Merrill Lynch
Group, Inc.

FAM is responsible for the management of the Fund's portfolio and provides the
necessary personnel, facilities, equipment and certain other services necessary
to the operations of the Fund. For such services, the Fund pays a monthly fee of
0.60%, on an annual basis, of the average daily value of the Fund's net assets.

Pursuant to the Distribution Plans adopted by the Fund in accordance with Rule
12b-1 under the Investment Company Act of 1940, the Fund pays the Distributor
ongoing account maintenance and distribution fees. The fees are accrued daily
and paid monthly at annual rates based upon the average daily net assets of the
shares as follows:

- --------------------------------------------------------------------------------
                                                  Account           Distribution
                                              Maintenance Fee           Fee

Class D ...................................        0.25%                 --
- --------------------------------------------------------------------------------

Pursuant to a sub-agreement with the Distributor, Merrill Lynch, Pierce, Fenner
& Smith Inc. ("MLPF&S"), a subsidiary of ML & Co., also provides account
maintenance and distribution services to the Fund. The ongoing account
maintenance fee compensates the Distributor and MLPF&S for providing account
maintenance services to Class B, Class C and Class D shareholders. The ongoing
distribution fee compensates the Distributor and MLPF&S for providing
shareholder and distribution-related services to Class B and Class C
shareholders.

For the six months ended June 30, 1998, MLFD earned underwriting discounts and
commissions and MLPF&S earned dealer concessions on sales of the Fund's Class A
and Class D Shares as follows:
