A fellow who works for me gave me the following information
about your turbo pascal problem. He is going out of town
for a while, but if you have any more questions, I will
give them to him when he returns.

Since  I'm a novice with this language, I can
only suggest solutions to  2  of  this  guy's
questions:

   1).  To turn the curson on/off, the guy
        should use some "In-Line" assembler
        code to make a call to the BIOS
        video routines.  I'll need my
        reference books to give you the
        specifics, so see me when I get back
        from Michigan.

   2).  Saving a graphics screen for future
        use should be exactly the same as
        saving a text screen except that
        you should save a full 16Kb (or
        32Kb for high res. stuff) rather
        than the 4Kb needed for a text mode
        screen image.
