How to resolve macro variable

thanikondharish — Tue, 17 Mar 2020 06:19:29 GMT

%let a=Peter;
%let b=jhonson;
%let peter_jhonson=salmon;

%put &&a_&b;

How to get salmon value

Maxim 48: The Dot, Always the Dot.

And, since two ampersands resolve to a single one, the first pass will result in

&a_jhonson

and a_jhonson does not exist as a macro variable.

This will do it:

%let a=Peter;
%let b=jhonson;
%let peter_jhonson=salmon;

%put &&&a._&b.;
