Hello,
%let X=5;
%let Y=X;
Can I recover the value 5 from the macrovariable Y ?
I thought &&Y.. would do the trick but it resolves to "X."
Thanks
OK, I have found the answer : add a third ampersand
%put &&&Y..;
5
I just don't understand the logic behind this.
The macro compiler removes duplicate &, "pairwise". In your case:
&& resolves to &.
&Y resolves to X.
Leaving &X, which resolves to 5.
Ok, that makes more sense now.
Thanks
Can be done, how depends on your application.
Simplest:
%let X=5;
%let Y=&X.;
