>It's arguable that viability of VFP5 depends on RESTORE FROM command. There are probably plenty of old-fashioned commands which will not work properly our days.

True. But I was told by Microsoft that a bug in that command was fixed in VFP 6, and we have yet to be able to get our application to cause an invalid page fault when running under VFP 6. So it appears that the bug that was fixed may have been our bug. If that bug still existed in VFP 6, we would redesign that part of our system and implement a different way of acheiving the same end result. Doable? Sure. But it would also represent a serious change to a core area of our system. Pretty risky.
