Re: MRP600 - BPCS 4.0.02

["Joe Green" <joegreen@xxxxxxxxxx>]

I'm sure this is not the case.

The files have been changed to contain (dates - 28 years).  The programs
have been modified to add 28 years prior to displaying or printing these
date fields.  Date fields have 28 years subtracted from them before being
written to files.

All of this is transparent to the users of the system.

Would you like to hear more about how this works?  Check out the website of
www.unbeatenpathintl.com .  They use this approach for Y2K issues.
