Zortech doesn't support extended memory directly.  You can program with
the Rational Systems DOS extender and Zortech C/C++ and do malloc()'s of up 
to 64 K until you run out of extended memory.  Which should do it for you.

Or you could use expanded memory and the Zortech _handle pointers.  This
will limit you to 16K per malloc() and dereferenceing a pointer is slower
(but nearly transparent to the programmer).  But you do have access to
expanded (not extended) memory without the cost of the DOS extender.

Yes.  :-)
