Re: ISO Dates

[boothm@xxxxxxx]

ISO dates and L-date fields are not the same thing.  You can use one, the 
other, both, or neither.  From what you describe I'd suspect you'd prefer to 
use the L-date field in your database and use regular 6-digit fields for the 
screens.  A move from *iso to or from *myd is not much coding, and it validates 
the date along the way.

What I did to figure this stuff out was to make a screen program with a couple 
of different kinds of entry fields and then a output fields of 6, 8, and 10 
columns, both alpha and numeric.  Then I wrote a program that took the keyed-in 
values and re-displayed them in all of the various display fields.  The program 
doesn't do much, so it is short and I could experiment until I'd figured out 
what was happening, where.  

To answer the 3 questions: yes, yes, no.
