Hi,
Also, if you use call symput instead of %let, then you can pass an expression or variable instead of a literal string. For example, instead of:
%let equation=(&Piece1/&Piece2);
you would use:
call symput('equation',&piece1/&piece2);
Please note that call symput only works within a data step, so you could do something like:
data _null_;
call symput('equation',&piece1/&piece2);
run;
Thanks,
Mark
