Good morning SAS aficionados -

I just posted some code to a thread that contains a headache I often have:

if (a=w & a~='') or (b=x & b~='') or (c=y & c~='') or (d=z & d~='');

or similarly:

if (a=b|a=c) & a~='';

The issue is that I want to check for non-missing equivalence between two (or more) variables simultaneously. Any comments on how one might simplify this?
