I have a series of files that I wish to concatenate ... named file01, file02, file03 ... file12.
If I use the code
set
%do i=01 to 12;
file&i;
%end;
;
the files are named file1, file2, ... file12.
How can I force the macro to use the 2-digit (zero-filled) form of the counter?
Thanks!
You can replace the value of I with a value with a leading zero inside the loop and it will not break the looping. You can then use &I where you need it.
%macro test ;
%do i=1 %to 10 ;
%let i=%sysfunc(putn(&i,Z2));
%put i=&i ;
%end;
%mend ;
%test;

Thanks to both Jaap and Tom ... I'm in business!
