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.
