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
