Hi everyone,
In the example below it makes a difference whether a macro variable is defined using CALL SYMPUT (here: &ab.) or %LET (here: &ab2.).
Why is that and are there any other noteworthy differences?
Thanks!
%Let a=1;
%Let b=2;
Data _null_;
Call Symput ('ab','%Eval(&a.+&b.)');
Run;
%Let ab2=%Eval(&a.+&b.);
%Put &ab.;
%Put &ab2.;
%Let b=0;
%Put &ab.;
%Put &ab2.;
