Subject:      Re: Setting a macro variable inside a macro.
Content-Type: text/plain; charset=ISO-8859-1

I assume that &subj is macro - local. You can define it outside the macro
and change its value inside, or you GLOBAL it.
The following might show the different ranges of variables:

%let outside=outside;
%macro test;
  %let inside=inside;
  %let globals=in and outside;
  %global globals;
  %put inside: &outside;
  %put inside: &inside;
  %put inside: &globals;
  %let outside=changed!;
%mend;
%test;

%put outside: &outside;
%put outside: &inside;
%put outside: &globals;

&INSIDE is a local varible and unknown outside.
