Hi Derek,
Great. That confirms my hopes that Visual FoxPro might someday become =
cross-platform. If Linux blossoms, Microsoft might find some good =
opprotunities going cross platform.

There's more truth in VFP being obsolete.

The great thing with C++(and I think C), is you can put assembler =
in-line in your code. This way you can do a specific loop or calculation =
in the absolute, most optimized(according to the developer) assembly =
possible-- and the compiler will just wrap it into your code untouched. =
I also see this quite often for MMX/SSE/SSE2 instructions...

There are many toolkits available for this.

Paul McNett was mentioning something about a QT toolkit. I believe =
this offered a common library to develop X-windows apps with.

Yes. All Win32 API calls would need to be changed to the appropriate =
UNIX calls, and any Microsoft-specific C/C++ language extensions(there =
are not many), if used in VFP source, would have to be converted to the =
equivelent in the compiler used on *nix.
