If people use date formats with 4 digit years additional work will NOT be
needed in the year 2039.

There have been some sessions presented by IBM'ers at COMMON which
recommended the use of *MDY date data types.  I would suggest UNDER NO
CIRCUMSTANCES should anyone use a date format of *MDY, *DMY, *YMD, or *JUL.

Also, look at the problem with PDM.  We say the AS/400 is Y2K enabled but
PDM F17 subset will fail to function properly at some point in the future
without further modifications because it uses a 2 digit year.  It didn't
work at all without a PTF.
