William,
Thank you for the suggestion. I changed the command.
DO IF ((SCHOOL#='17114' AND GRADE='00' AND RUNREC>1)AND SYSMIS(LETTER)
AND SYSMIS(PRINT)).
COMPUTE LETTER=52.
COMPUTE PRINT=16.
END IF.
EXECUTE.
I don't get an error message now. Another problem came
up.When I check the data, I found that all the value of the variable
print had been changed to 16 while the value of letter remained
unchanged at all no matter what the original value of letter and print
are.
I am puzzled.
