Hello Rob,

Yep.  Well spotted.  That's a defect.  The format is a required parameter
so the sample calls won't even compile.  As I said, I didn't test any of
it (or even compile it) -- just verified it with the manual.

Forgive?  What's that?  :)  I could have made theFormat optional and used
the default format for the job but that would have taken more code to get
the current date format and I couldn't be bothered for this example.

Exactly.  Given that there can be only one format, and the formats are
tested in a SELECT block (therefore only one WHEN clause will evaluate to
true), I could have coded:

        RETURN          NOT(%ERROR)

but I thought that might cause more confusion so I opted for the obvious.
