RE: Ok here is a challenge

Kinda, sort of, wondering if anyone was able to come up with the answer or
an answer.

I am not familiar enough with creating commands to know how to do it, and I
did not know how many on here actually know how its done, not to imply
anything, just thought it might be something of value if someone who knows
would share some ideas with the rest of us with a sponge for a brain.

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?
