NAME
  STRIG, ON STRIG Statements

SYNOPSIS
  STRIG(n%) ON
  STRIG(n%) OFF
  STRIG(n%) STOP
  ON STRIG(n%) GOSUB line
      o n%                A value that specifies a joystick trigger:
                          n%    Trigger
                          --    -------------------------
                          0     Lower trigger, joystick A
                          2     Lower trigger, joystick B
                          4     Upper trigger, joystick A
                          6     Upper trigger, joystick B
      o STRIG(n%) ON      Enables joystick event trapping.
      o STRIG(n%) OFF     Disables joystick event trapping.
      o STRIG(n%) STOP    Suspends joystick event trapping. Events are
                          processed once event trapping is enabled by STRIG ON.
      o line              The label or number of the first line of the
                          event-trapping subroutine.

DESCRIPTION
  STRIG, ON STRIG Statements
  STRIG enables, disables, or suspends joystick event trapping.
  If event trapping is enabled, ON STRIG branches to a subroutine whenever
  a specified joystick trigger is pressed.

  Example:
      'This example requires a joystick.
      ON STRIG(0) GOSUB Handler
      STRIG(0) ON
      PRINT "Press Esc to exit."
      DO UNTIL INKEY$ = CHR$(27): LOOP
      END
  Handler:
      PRINT "Joystick trigger is depressed."
      RETURN
