In Lightspeed Pascal, there are two resources that tell which
areas of low memory are not shared between Lightspeed Pascal and
the current project; these locations are swapped back and forth
between LSP and your project whenever LSP does a context switch.
Resource QPRF 2 gives these locations if you
'are using the old 64K ROMs, and QPRF 3 gives the locations
if you're using the newer ROMs.

You can modify these resources, in order to save additional
low-memory globals. In my case, I had a program that
called SetResLoad(FALSE) before entering a loop, and
called SetResLoad(TRUE) after exiting. Problem was, I had
a minor bug inside the loop, and when my program failed,
LSP reported the error and promptly crashed; ResLoad was
false, so LSP couldn't get the resources it needed to properly
report the error and put the thumb at the bad line.

I fixed this problem by creating a ResEdit template to edit the
QPRF resources, and adding the address of ResLoad ($A5E) to the list.
Now things work nicely.

Anyway, since the patch is so small, here's the BinHex of it:

(You may have to take out the blank lines)

The TMPL resource should be pasted into ResEdit before you try
to edit the QPRF resources; the QPRF resources
are the ons I've patched to save ResLoad; they can be pasted intoh
Lightspeed Pascal.

If you want to modify the QPRF resources further, read chapter 14 of
the user's guide for LSP.

As always, mess around with a COPY of Lightspeed Pascal, and use LSP
for a bit to be sure that you didn't mess anything up.
