Hi, Mayukh,

Unless your %iterate macro resolves to some data step statement(s) that
can safely be looped, the above approach would not work. You can iterate
calling it using a macro loop like below, though. HTH

Cheers,
Chang

%macro iterate;
  %put Hi;
%mend;

%macro hundred;
  %local i;
  %do i = 1 %to 5; /* change this to 100 */
    %iterate
  %end;
%mend;

%hundred
/* on log
Hi
Hi
Hi
Hi
Hi
*/
