I'd discourage going down the road of comparing strings to

MAX_SHORT_STRING. You could just get unlucky and be processing a
string that happens to have the same bit pattern as SYSMIS.
I'd check the variable type before making that comparison.
OK. Done. Henceforth I shall assume that string variables can never
be SYSMIS.
Incidently, while you're reforming variable.[ch], how about prefixing
the symbols NUMERIC and ALPHA with VAR_ ?
