Isn't it interesting how a worthless language can have so many nice 
features?

Honestly, I don't think I'd want to invoke an executable image each time 
some keyboard entry happens.  Just seems inappropriate to me ....

I don't know the application, but as I don't consider DCL a programming 
language, perhaps implementing the application in Basic might be an option?

I think Paul Sture gave the best solution, and Steve's idea of testing 
for "allowed" rather than "disallowed" was also good.
