Even discounting for a statistical bounceback from the 1988 drought, a major factor in the overall increase, the gross national product grew at a solid 3 percent annual rate during the January-March period, the Commerce Department reported.
The stock market's response was inconclusive, with stock values drifting in a narrow range. The Dow Jones average of 30 industrials edged up 2.20 to 2,3889.11.

The nation's total output reached an annual rate of $5.117 trillion last quarter before adjusting for inflation, the first time it had exceeded $5 trillion. After adjusting for price increases, the GNP rose at an annual rate of $4. …
