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 presentthe 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?
