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?
