Svend's idea will not work at all, as my two identifiers
are not meant to take the same values. That is, g1 will
likely never equal g2.
 
C�lio's suggestion does get at what I want, especially as
it found no errors. However, I'm curious if there is a way
that would also let me identify which records or values
produced the errors;  -assert- is uninformative in that
respect.
 
=========================================================
 
I see. A combination of C�lio's and my ideas comes here:
 
   bysort g1: generate same1 = (g2[_n]==g2[1])
   bysort g2: generate same2 = (g1[_n]==g1[1])
   tab1 same1 same2
   list if same1==0 | same2==0
 
Good luck
Svend
