I have one across field that has two pieces of data: 06/30/2012 and 09/30/2012. How can I compute the difference of the two dates in a column shown after the across data?

If you know your column numbers, you can put a compute after the across statement. Something like:

SUM PROFIT
ACROSS QTR
COMPUTE DIFF/D12.2=C2-C1;

Patricia, That's about as succinct as it gets.

Thanks, I was trying to keep it simple and not confuse a newbie. You know as well as I that this can still be done even when you have more than 2 quarters (an unknown number) but the logic becomes much more complicated.
