Hi Quentin and Karl,
The following program shows, that macros and macro variables are not
resolved within comments.
Run it once like this and once with an empty macro variable FirstCh.
===========================
%LET FirstCh = *;
%MACRO Comment; CALL EXECUTE ('%LET MacroRun=Macro run;'); %MEND Comment;
%LET Comment = CALL EXECUTE ('%LET Resolved=Macro value resolved;')%STR(;);
DATA _NULL_;
&FirstCh %Comment;
&FirstCh &Comment;
RUN;
%PUT MacroRun=«&MacroRun.»;
%PUT Resolved=«&Resolved.»;
===========================
Regards - Jim.
