If you want to find out what's in memory at a particular location, and
you're lucky enough to be using a Zenith computer (at least, on every
Zenith I've seen except the Eazy-PC -- it had a non-Zenith BIOS), you
can press ctrl-alt-return (enter, whatever), at pretty much any time,
and be thrown into what Zenith calls a "monitor program" -- the same
one you get when you press ctrl-alt-ins.  Only in this state, it shows
you the memory contents at the current location.  You can change,
examine, etc. from this point.  If you type "g" and press return,
you'll go back to executing the program where you left off, assuming
you didn't mess with anything important.  It's essentially a built-in
debugger.

Apologies to anyone who doesn't have a Zenith, but look on the bright
side, this feature can cause incompatability problems on rare
occasions.
