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

     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_ ?
