You're going to find that at least SOME things are going to need re-writing
anyway. Some things just flat-out work differently in DOS and Windows.
(Printing springs to mind. <g>) Likewise, some coding techniques used in DOS
apps (printing springs to mind <g>) work differently if at all in Windows.
It's a simple fact of life. Some code techniques (such as @....GET) are
deprecated.

Microsoft *says* your 2.x code will run unmodified in VFP, and it may. Then
again, it may not. We're talking about vastly different programming
environments with vastly different expectations.
