Snicker.

The MCH error would occur as soon as you set the pointer, if the limit
was somewhere between the current pointer and the new offset.  Maybe
if your space is auto-extendable (is that possible?) _and_ you don't
go over whatever is the absolute size-limit for a space, then maybe
you won't get an error.

But I know it's possible to get a MCH0601 from doing what you're doing,
because I used to do it that way too, until I got the MCH0601.  My program
was working fine until I had some huge number of entries, and got near the
end of the space.

"Seems to be working" is usually the case with programs that use pointers
illegally.
