Dear Morris,
First of all (and to everyone posing problems to SAS-L): do not state a
subject like "question" or "help", because that is what it is about always.
Just describe your problem more to the point, e.g. "processing data and
lag".
Secondly, I do not understand what you would want to do with your first
problem. I can't see any logic in what you state on point of departure and
desired result.
Your second problem can be solved from within a macro by the following
lines, replacing your assignments of var 1 to var10:
%LOCAL I;
%DO I = 1 %TO 10;
var&I=lag&I(aa);
%END;
Regards - Jim.
