More date questions

["Phil" <sublime78ska@xxxxxxxxx>]

All,

I need to know whether one of two dates is in a prior month.  I found this
won't work:

    from = d'2001-07-31';
    to   = d'2001-08-01';

    diff = %diff(from:to:*months);

Diff = 0 in this case.  To me, I'm counting months - not how close the days
are.  But ok.  So I did this (which works):

 if %subst(%char(from):6:2) < %subst(%char(to):6:2);
  priorMonth = *on;
  else;
  priorMonth = *off;
 endif;

My question is:  Is this the correct way to determine if one of two dates is
in a prior month?

Thanks,

Phil
