Ouch!!!   :-(

I think I disagree with your approach. "Niceness" usually means "something
that can't be maintained", as you've suggested. What is the cost in time
(=$$$$$$) when there are tricky techniques in place?

It seems you want one monolithic program to validate all commands. This is
not, IMO, AS/400-ish. It's not even modular or structured technique. But I
could be wrong.
