How to Convert a number to character ID#

[KoKo312]

DATA FINAL;

SET WORK.EMSM;

PARENT=CHILD;

I've tried several different ways Rename, Attrib, Format functions and nothing is working. The child values are 4 digits (ex.0001).

HERE'S MY CODE

Data final (RENAME=(CHILD=CHILDnum));

SET WORK.EMSM ;

PARENT=CHILD;

CHILD=PUT(CHILDnum, 4.);

DROP=CHILDnum;

RUN;
