Thanks for providing the Forth background to all this.

Another source of code (slightly different) is
http://vf-plugins.googlecode.com/files/pfDatabase-4.zip

A note to anyone wishing to convert the above code to a modern Forth
dialect.  PolyForth's modulus functions were all *unsigned*.  Thus,
to calculate day-of-week on a modern 16-bit Forth one would need
0 7 UM/MOD DROP  rather than  7 MOD.  Similar adjustments in
the code may be required.

As the buggy Lotus/Excel implementation is now widely in use, there's
a case for having that also.  I understand Hans has implemented some
functions for 4tH.
