Hi all,

Can I use  the 'and' 'in' 'not' 'or' operators in %macros?

Say I have these possible macro resolutions: YES yes YeS yeS and I want to
evaluate each expression collectively and move forward:
I.E :

%if &yesno IN (YES yes YeS yeS) %then %do;
      more code ......
%end;

OR  should i do something like this:
 %if %upcase(&yesno)=YES then %do;
      more code....
 %end;

Maybe I answered my own question.
But I'm just not sure about operator usage in the macro language

Thanks.
