    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.
