Easy. Create a ID say numeric X by a do loop first, 1,2,3….. then convert it to char and pad with leading zeros using Z6. format. Finally, combine them together. You get it?

Data AAA;
Do X=1 to N;
ID= “aa59” II put(X, Z6.);
Output;
End;
Run;

Use nobs option, or _N_, or a macro variable. It depends on what you need.
