A string of alphabetic characters which alter how %DT
responds. Briefly stated, the acceptable characters are:
A Ask for date input.

I Internalization, assumes the day precedes the month in input.
M Only Month and year input is allowed.

R Requires time input.
S Seconds should be returned.
T Time input is allowed but not required.

X is always returned. It contains either what was
passed to %DT (in the case where %DT did not contain an A) or what the user
entered.

(Optional) A prompt which will be displayed prior to
the reading of the input. Without this variable, the prompt "DATE:" will be
issued.

Input |
The default answer to the "DATE:" prompt. It is your
responsibility to ensure that %DT("B") contains a valid date/time.
|
%DT(0) |
Input |
(Optional) Prevents the input date value from being
accepted if it is chronologically before, or after, a particular date.

of two values:
Y=-1 The date/time was invalid. Y=YYYMMDD.HHMMSS The value determined by %DT.

This is only defined if %DT has timed-out waiting for
input from the user.
