Before people run out and buy the wrong thing, VROOM comes in the latest
Turbo Tools package, and in Turbo C++ (not Turbo C v 2.0) which also has
a C compiler option. 

There is a compilation switch you must use to use VROOM. Therefore you cannot
use VROOM with Microsoft .OBJ's. You must use Turbo C++ (or its C option) and/
or TASM.

Also, only code segments can be swapped. Data segments must always be resident.
