"Why did you use a RETAIN statement for B321 if you did not want the values retained? Why did you use a RETAIN statement for NATBAT when it already exists in the dataset SASHELP.BASEBALL?" Because I'm ignorant. That doesn't entitle you to be condescending.

Could anyone tell me why this sometimes happens if I do not explicitly include an else statement? I was expecting b321 to only equal 1 for nAtBat=321. Most of the time I have no problems with this, but once in awhile I spend half the day troubleshooting and am usually so fed up that I just add all the else statements and say good riddance. But I would like to understand why this happens. To be clear, nAtBat is the 2nd field. I appreciate any input! data bb;
retain b321 nAtBat;
set sashelp.baseball;
if nAtBat=321 then b321=1;
