Ron, I'm sure you've probably come across my suggested technique, but for
the benefit of those that haven't I will document it herein:
%macro numobs(dsn);
%global numobs;
%if %upcase(&dsn)=%str(HELP) %then %do;
%put HELP: CODE YOUR MACRO DOCUMENTATION HERE E.G.
%put HELP: NUMOBS should be invoked with a valid SAS dataset;
%put HELP: name e.g. %nrstr(%NUMOBS(SASDATA.CHKFILE)).;
%put HELP: Note: The LIBNAME must already be assigned.;
%end;
%else %do;
%* Macro statements here;
%end;
%mend numobs;
Regards
