RE: Ok here is a challenge

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.

Doug,

Check out the VLDCKR (validity checking program) parm on the CRTCMD 
command. This allows you to specify further validation programs before the 
main control program is called. More information can be found in the CL 
Programming guide. SC41-5721

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?
