>Hi Christof,

>And you would so if it pays off. I have no doubt that Microsoft would rewrite the kernel, if they gain more by doing so than they would gain by doing something different (as long as there are no political issues involved). It's just that I can't see what Microsoft would gain. I don't have the source code of VFP, maybe it is really impossible (or difficult) to take the existing code over to a 64 bit OS system and I really hope so, because then there's a business reason to re-write the kernel. But if it's easier to take over existing code, Microsoft would probably do so, no matter how great a re-write would be.

One thing that I haven't mentioned is IDE. How does the current VFP implementation of Windows messaging fit it with that concept? Not terribly well, I'd imagine. However, this is SWAG. I don't know for certain. It may be the overriding factor that decides this one way or the other, however.

A note to JimB. You're absolutely right (of course) about n-tier, it's meaning and implications. I'm guilty of using some rather sloppy nomenclature. I should have said, "all VFP solution" rather than "single tier". Please don't make me watch "Barney" as punishment< bg >.
