I just received an upgrade order form from Zortech, for version 2.1. 
Two of the advertised new features which seem unclear to me are:

    1. Virtual code manager, which is supposed to let you write programs
       up to 4 megabytes in size in real mode.

    2. Rational systems Dos extender, which is supposed to let you write
       proprams which access memory beyond 640k.

If you have 1., why would you need 2.?  Does anyone know more about these
features?  Would they let you write programs whose data is about 2-3 mbytes,
without worrying about expanded memory, and without using the __handle?
How does it compare to the facility of Turbo C++ which provides virtual
memory (in a way)?
