 Thank you for the suggestions, and if I want a macro taking the macro
variable as parameter, then how to revise the following code.

%macro batchcodeA (param);
  %do i = 1 %to &nvisit;
   %let vis_a = %scan(&vValList, &i, %str( ) );
    %do j = 1 %to &nvisit;
    %let vis_b = %scan(&vValList, &j, %str( ) );
             &param
    %end;
  %end;
 %mend;

%batchcodeA(%nrstr(STD_&vis_a.&vis_b))

Thank you for your help.

Best regards,
Amy
