I'm assuming you actually used semicolons to end your statements, and you merged using a MERGE statement rather than a SET statement.

 

The basic problem is that you have a common variable, SUBJECT, in both data sets.  There are a couple of ways to deal with that.  To ignore all SUBJECT values in one data set, you could just drop it:

 

data final;

merge new (drop=subject in=a) new1;

by name class;

if a;

run;

 

I would assume you are merging by both variables, and not just by NAME.

 

The problem gets a little more complex if you need to compare the SUBJECT values in the two data sets, to see which you want to use.

 

Good luck.
