TIMER enables, disables, or suspends timer event trapping.
If event trapping is enabled, ON TIMER branches to a subroutine whenever
a specified number of seconds has elapsed.
 
TIMER ON
TIMER OFF
TIMER STOP
ON TIMER(n%) GOSUB line
 
    - TIMER ON      Enables timer event trapping.
    - TIMER OFF     Disables timer event trapping.
    - TIMER STOP    Suspends timer event trapping. Events are processed
                    once event trapping is enabled by TIMER ON.
    - n%            The number of seconds that elapse before ON TIMER
                    branches to the event-trapping subroutine; a value in
                    the range 1 through 86,400 (24 hours).
    - line          The label or number of the first line of the
                    event-trapping subroutine.
 
Example:
    ON TIMER(1) GOSUB TimeUpdate
    TIMER ON
    CLS
    PRINT "Time: "; TIME$
    StartTime = TIMER
    WHILE TimePast < 10
        TimePast = TIMER - StartTime
    WEND
    END
 
    TimeUpdate:
        LOCATE 1, 7: PRINT TIME$
        RETURN
