    DON'T DO IT.  It's *very* bad technique, and your application
    won't run, besides.

To answer your question: You can change the pointer's location by
changing low-memory global variables.  Which ones?  I'm not sure; how
you access them depends on what compiler you're using.  I'm not
familiar with THINK Pascal.

Be warned that an application that changes low-memory globals has
written its own death sentence.  It will do nasty things to systems.

Besides, to have a program move the pointer for you is like having a
robot grab your hand and move it around for you.  The pointer is the
user's `hand': he should have free, unconstrained movement of it at
all times.

Tell me what, exactly, this `good purpose' is that you've thought up,
and I and millions of other Netters will help you come up with a more
proper way of doing it.
