DTC Rev 2

	The DTC program is now revised to provide the
following new functionality:

1. Year at a glance (courtesy Mitch Wyle)

2. Default date and time remain as last set now, permitting
	switching among day/week/month displays
3. The new I command resets default date to today

4. Command D saves appointments in the current file only, not
	in any files indirected from the current file via the
	99999999filename.typ= format.
   Command S (schedule) saves appointments entered that way in
	files indirected, but not in the current file (leaving
	a file of indirection pointers clean).
   Command G saves appointments in both.

5. Dates may be entered in format
	mmddyy		(as before)
	mm/dd/yy	(new, easier; mm and dd may be 1 digit long)
	dd-mmm-yy	(dd may be 1 digit long. mmm text is parsed
			only enough to disambiguate months.)

Also, the Week display does a better job now when showing appointments
in a first week of a month where the month changes during the week. It
appears completely correct now. Also the month display has been upgraded
to not overflow the screen on long months with 6 lines for weeks.

	DTC Rev 3

	DTC now contains the new function
 + nnU
 - nnU
	where U may be D,W,M, or Y for Day, Week, Month, or Year.
This command changes the default date by the specified increment
and leaves the display alone. The default for U is the last display
mode, and the default for nn is 1 so that if just a + or - is seen,
the default is to move 1 unit.
