Ok. I admit I'm responsible products, not application programs, and can never count on a use being "well behaved". Perhaps this makes me more paranoid than you.

But your argument works both ways. If an appllication programs is well behaved and doesn't ask for unlimited storage, there is a a region size that it will not exceed. It's therefore safe to set a REGION parm that will let it execute normally yet catch it if it goes bananas. (I'm obviously not talking about 822s here - more like 878s, etc.)
