Hi Patty,

%trim maybe works.

%let IndepVar=%nrstr(AAAAAA         );
%let i=%nrstr(BBBBBB         );

title1 "Raw Data: Varying &&IndepVar&i*****";
title2 "Raw Data: Varying %trim(&&IndepVar&i)*****";

proc print data=sasuser.heart(obs=2);
run;

-OUTPUT-
Raw Data: Varying AAAAAA   BBBBBB   *****
Raw Data: Varying AAAAAA   BBBBBB*****

Kind Regards
Zibao Zhang, MD
