Y2.1K Compliance

May 1, 1925 would be represented as 0250501 in CYYMMDD format.  The C
value of 0 does cover all of 1900 to 1999, 1 2000 to 2099, etc.

What's confusing you, I suspect, is that the combination of QCENTURY,
QYEAR, QMONTH, and QDAY represent what the current date of the system
is and the system (current release and all that) only supports an IPL
date ranging from August 24 1928 to July 6 2053.  This limit on the
range of QDATE does not mean that CYYMMDD formats have the same limit.

I want to stress that this does not mean that application dates cannot go
beyond 2053.  Using 4-digit date formats applications can support dates from
year 0001 to year 9999 with no problem.
