Marc,
That's a good point. Most of us have been using a 1900-1999 window for years. Using SET CENTURY ROLLOVER is actually an improvement because you can adjust the window based on the current date.

>Let us face it, if your system spans over more than100 years, you have to have 4 digit century date entry. If you did not had that in the past, it is unreasonable to require it now, because you were windowing already.

>And even if you enter 4 digit century dates, stricly mathematically, you're still windowing :).

>>>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).

>>Thanks for the enlightenment, guys. I guess I'm guilty, then :) Our reqs are for 2-digit year entry, so we need to use ROLLOVER. We're not the only office using this method for date entry, it's pretty standard, so I have company in my grumbling.

>>To make the IG happy, I have to admit I'm Windowing, fill in a new section of the compliance form, and redo my test plan and results a little. Not a huge deal, but I just wanted to make sure I really needed to. People in the Y2K certification office readily admit that the IG's upper management office know very little about computers...
