NAME
  TIMER, ON TIMER Statements

SYNOPSIS
  TIMER ON
  TIMER OFF
  TIMER STOP
  ON TIMER(n%) GOSUB line
      o TIMER ON      Enables timer event trapping.
      o TIMER OFF     Disables timer event trapping.
      o TIMER STOP    Suspends timer event trapping. Events are processed
                      once event trapping is enabled by TIMER ON.
      o 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).
      o line          The label or number of the first line of the
                      event-trapping subroutine.

DESCRIPTION
  TIMER, ON TIMER Statements
  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.

  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
