Calculating with times
The functions
HMS, HMS , HMS+, and HMS- are used to manipulate
values in the HH.MMSS format. This is the same format used to calculate with
angle measures in degrees, minutes, and seconds. Thus, these operations are
useful not only for time calculations, but also for angular calculations.
Examples are provided next:
Alarm functions
The sub-menu TIME/Tools.../ALRM... provides the following functions:
The operation of these functions is provided next:
ACK:
Acknowledges past due alarm
ACKALL: Acknowledges all past due alarms
STOALARM(x): Stores alarm (x) into system alarm list
RCLALARM(x): Recalls specified alarm (x) from system alarm list
DELALARM(x): Deletes alarm x from system alarm list
FINDALARM(x): Returns first alarm due after specified time
The argument x in function STOALARM is a list containing a date reference
(mm.ddyyy), time of day in 24 hr format (hh.mm), a string containing the text
of the alarm, and the number of repetitions of the alarm. For example,
STOALARM({6.092003,18.25,"Test",0}. The argument x in all
the other alarm functions is a positive integer number indicating the number of
the alarm to be recalled, deleted, or found.
Since the handling of alarms can be easily done with the TIME menu (see
above), the alarm-related functions in this section are more likely to be used
for programming purposes.
