After looking at this post a bit further, I think it is important to bring up an important point......any modification to the Visual FoxPro runtime is a violation of the license. When I first read this post - I did not realize the ESL was being modified.

That said, I would ask that you cease offering this solution......



>THE ULTIMATE FOXPRO Y2K SOLUTION

>Well guys/gals here is what I believe to be the ultimate Y2K solution for FoxPro 2.5 & 2.6 for DOS and Windows.

>The other day an associate of mine called me up and informed me that he has successfully developed, and installed at some of his customers locations, a patch for the FoxPro ESL runtime that gives it the same capability as the ROLLOVER in Visual FoxPro.
>
>What happens is your ESL file gets patched so that the DIFFERENCE() function, he had to put the code somewhere, is non functional but that all dates rollover based upon a year that you specify. For example say you choose 50 as the rollover year, when someone enters a date with the year of 51 or greater then 19XX is used but when you enter 50 or less then 20XX is used.

>Directly patches development EXEs and runtime ESLs
>No need to have access to source code
>No TSR/preloading executable
>No need to change shortcuts/batch files to preload a patch file

>No "per seat" charge
>Handles 02/29/2000 same as Visual FoxPro with ROLLOVER
>You will have the same freedom to distribute the patched ESL as the
