Re: a smart way to display null date fields on screen

You have some good answers on how the display will work so I won't repeat
that advice.  What I will respond to is the 'null date field on screen' in
the subject line.  If the date field is truly null, you need to test it with
%nullind or a null map (depending on how you are retrieving the data.)  NULL
is not a data value like '01/01/0001', rather, it is an attribute of the
field which can be changed at run time.  If the field is NOT truly NULL
(that is, ALWNUL is not specified in the DDS) then you need to be aware that
the database design is using 01/01/0001 as a special value, which is when
MAPFLD is most useful.
