Numerics in SAS have the leading zeros stripped. So you have to convert them to character and use the Z Format.

C = Put( A , Z3. -L ) || "_" || Put( B , Z4. -L ) ;

Better yet if you are using SASV9 use one of the Cat functions:

C = CatX( '_' , Put( A , Z3. ) , Put( B , Z4. ) ) ;

Your other questions answer is :

A = Put( , Z4. ) ;

Compromise is like telling a lie, it gets easier and easier. Each comprimise you make, that becomes your standard.

Perfection doesnt exist, once you reach it, its not perfect anymore. It means something else.
