RE: Ok here is a challenge

No I am not asking if it is possible, I know this guy and if he says it is,
then I take it at face value.  I am asking if anyone else here has done it
and if so, would they mind sharing it with some others.

He specifically said he was not referring to validation programs, that it
can be done entirely from within the command itself.

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?
