Yes. Wonderful little macro. I think I got it off a SUGI paper, but unfortunately I didn't put the source in my code. (My apologies to the author) -Venita

%macro delvars; *clears out all global macros; data vars; set sashelp.vmacro; run; data _null_; set vars; if scope='GLOBAL' then call execute('%symdel '||trim(left(name))||';'); run; %mend; %delvars
