 TS> Hi Dale,

Hi, this is from the guy who did the patch you are referring to: Nancy's
husband.

 TS> I used your full .EXE patch. Nice work! I was reading your .DOC file
 TS> on it and you mention something about the C libraries expiring in 2038. Can
 TS> you elaborate on this?

In the old C libraries, time/date is kept as a count of seconds from
1970 in a 32bit signed integer.  That means that the "date" will roll
over from positive to negative in January 2038 - and programs using it
will break.  Newer C libraries use an unsigned 32 bit integer and will
work for twice as long or to 2106 (newest use a 64 bit integer...). 

 TS> Also, what "OTHER" 3rd party libraries will the patch work on??

Not libraries, but 3rd party programs.  I've used it on the DOS Pegasus
Mail utility PREBUILD.EXE and one or two other programs.  The only
requirement is that they were built using one of the Borland C Libraries
I made a patch for.  You will know that it works when you get at least 4
"1 changes made" messages when running the batch file. 

 TS> Thanks Dale!

You are welcome, and thank you (Richard).
