Bruce,

Windowing is exactly what ROLLOVER does. It's when you set a range of years to be interpreted 19xx and another to be interpreted 20xx. A couple of points you may want to make:

1. If you have SET CENTURY ON users don't have to rely on "windowing." It's only in effect if they don't enter all four digits of the year.

2. Some systems that use windowing still store only two digit years. The windowing is used every time a date is interpreted. VFP stores all four digits and only uses windowing when the user (or developer) provides only 2 digit years.

If they still won't go for it you may need to stop using ROLLOVER. If you do this you'll probably want to force users to enter all four digits. I know that Christof Lange had a good suggestion for how to do that. If you search the messages you'll probably find it. I think it was January of February '99 (I mean 1999 :D).

>My Vfp Y2K compliance was kicked back for repairs because the Y2K Inspector General said using ROLLOVER was a form of Windowing, which they do not like. I'm not even sure what Windowing is, though I've heard the term used many years ago, in regard to mainframe interface, I believe.
