Doug - sorry I'm not too sure what question you are asking. Are you trying to confirm if this is possible - or - are you asking if this is used. For myself - it depends upon what you are asking the command to do. Have I used a command validation program? The answer is yes, but not always.

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?
