No additional program, he is saying that it can be done in its entirety from within the command itself. -----Original Message----- From: rpg400-l-bounces@xxxxxxxxxxxx [mailto:rpg400-l-bounces@xxxxxxxxxxxx] On Behalf Of Coyle, Stephen F.

I am aware of that, but he specifically said that is not what he is referring to, he is saying that it can all be done from within the
command
itself and not require another program. -----Original Message----- From: rpg400-l-bounces@xxxxxxxxxxxx

This allows you to specify further validation programs before
the
main control program is called. More information can be found in the

Latham, NY 12110 gary_jones@xxxxxxxxxxxxxxxxxx (518) 951-1037 "Douglas Palme" <dpalme@xxxxxxxxxxx> Sent by: rpg400-l-bounces@xxxxxxxxxxxx 03/07/2007 09:48 AM Please respond to RPG programming on the AS400 / iSeries <rpg400-l@xxxxxxxxxxxx> To "'RPG programming on the AS400 / iSeries'" <rpg400-l@xxxxxxxxxxxx> cc Subject Ok here is a challenge I received this from one of our RPG gurus and I thought I would
present it
to the midrange group and see what ya'll thought: There is a way to completely control the input from a command and
validate
it before the program is actually called. There is also a way to
present
the actual valid parameters without hard-coding anything. As an example
you
could have a command that takes a division number and if you do not
enter
a division that exists in the DIVISION file it will not accept the
value.
This is true for anything you want to validate, a date, time, printer, username, etc. Most programmer shy away from writing powerful commands as they
do
not understand them. Anyone?
