Looking at your message again, I think I misdiagnosed the problem, as you 
are already using the char command (although for religion, SPSS's default 
would be to use "None" as the reference, and for Cath the default reference 
would be Catholic).  So now I am wondering about this e5c variable; is it 
basically just a recoded educ5, e.g. ec5 = 3 - educ5?  If so, that might 
account for the seeming problem.
