I have the following code segment:
%if (&alist=a.*) and (&blist=b.*) %then %do;
ERROR: A character operand was found in the %EVAL function or %IF condition where a numeric operand is required. The condition was:
(&alist=a.*) and (&blist=b.*)
Basically it is the * that caused the error. I would like to compare if alist value equal to a.* and blist value equal to b.*, how to achieve this without error?
