Beginning, End & Duration
The [Beg], [End] and [Dur] keys are used to
calculate starting and ending times as well
as duration of time. Given two values, the
third can be easily found. You may enter
a whole number, a point in time or a
period of time into the [Beg] and [End] reg-
isters. Only periods of time can be
entered into [Dur]. AM/PM entries for
duration cause an error.
