Are you allowed separate wrappers for DOS and Win32?

I don't really see the problem. ProForth for DOS runs fine under all DOS
versions, and under all versions of Windows. The same binary! The same
wrapper! See the new low, low prices on the website.

If you want to run the same binary either as a Windows console app
and under DOS then you may need to make changes. However, if all
you want to do is to capture DOS program output in a Windows app,
then we can help you already. Our VFX front ends can do this
already.
