Formatting counter in SAS macro

DanWALDO — Tue, 08 Apr 2014 17:09:43 GMT

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;
