Well, I hate to disagree with you, but it can be done. In fact, it has been
done. Mike Scott has written an interface unit, which is included below. The
unit can also be downloaded from CompuServe (BPASCAL forum) and will be
included on the disk with The Pascal Magazine #5 which includes some articles
on using WinG from Borland Pascal.

Anyway, here's the import unit from Mike (I think a newer version will be on
The Pascal Magazine disk):
