THANKS IN ADVANCE.
 
I HAVE TWO EXTERNAL FILES AND THEIR ATTRIBUTES ARE
      DSORG=PS
      RECFM=VB
      LRECL=99
      BLKSIZE=27998.
 
EXTERNAL FILE1 HAS 3 VARIABLES:
 UID in col. 2 for  a length up to 7 bytes.
 NAME, and GROUP are the other 2 variables that I don't need.
 
EXTERNAL FILE2 HAS 1 VARIABLE:
 UID in col. 2 for  a length up to 7 bytes.
 
External file1 contains the "good" userids.
External file2 contains  the "bad" userids, i.e., userids that will be
deleted (allegedly).
 
My question is how do I compare External file2 against External file1 to
ensure that External file2 doesn't contain any "good" userids.
I apologize if I was too long-winded.
Again thanks.
