Kindly explain me how to know a variable is macro or a data set variable.
Thanks,

Macro: can be used both in open code (outside data step/proc) or within a data step.
Data step variable obviously only available within a data step.
Macro variable assignment:
%let macrovar = Hello;
Macroa variable evaluation:
data good;
if "&MacroVar" = 'Hello' then....
run;
by the nature of you questions, I think you need to take som basic SAS classes to understand the conepts of SAS.
Even if the purpose of these forums is to have the possibility get quesrtions answered, I think that basic questions that easily can be answered by looking in the documentation or to be taught in SAS classes should be avoided.
