Data is not swapped with VCM, only code is. You can swap data if you use
__handle pointers and EMS.

To develop DOS extender apps, you'll need the DOS extender from Rational
Systems. However, it is 'plug and go', you'll not need to patch the
libraries or otherwise mess around with the compiler to get it to
work with the DOS extender. The FG graphics libraries also work right
out of the box with the DOS extender.
