I hava a sas dataset imported from Access. All three vars: Grade, class, and group are numerical with both format and informt are best8.. Supposing following is the value:

Grade class group 1 1 1 8 10 13 12 11 10

What I want to do is to get a new numerical var(ALL) by combining these three variable and make it compariable. That is:

Grade class group all 1 1 1 010101 8 10 13 081013 12 11 10 121110

So I want to add leading 0 to these three vars to get the expected value of ALL. After that, I can choose records by compare ALL. For example, I will extract records where ALL>081010. Then 2 and 3 will be selected.

So how to make this? I tried following: grade1 = put(grade, z2.);

But when I check, the grade1 is character but not numerical var. If any expert can provide your valuable suggestion and advice, it would be greatly appreciated. Thanks again.

Regards, James
