Re: Y2.1K Compliance

Hi Bruce,

No problem except the limitation on entering 4-digit year dates in a command
parameter, at least according to the help text:

"When entering the command, the year may be specified with either 2 digits
or 4 digits.  If a 2-digit year is specified, the date is assumed to be in
the range of January 1, 1940 through December 31, 2039.

If a 4-digit year is specified, the date may be in the range of August 24,
1928 through May 9, 2071.

When it is passed to the command processing program, it is always passed in
the format Cyymmdd, where C = century, yy = year, mm = month, and dd = day.
The century digit is set to 0 (zero) for years 19xx, and it is set to 1
(one) for years 20xx."

So if an application depends on a command for entering a date for any
reason, they will be limited to 08/24/1928 - 05/09/2071 instead of
01/01/0001 - 12/31/9999.
