Toggles frame looping on and off.
To start automatic frame looping,
Pressing L a second time stops the looping at the first frame of the loop.
The L command works only if the loop control system is connected to the frame system.
The Y and J commands connect (and disconnect) the image and graphics frames to the loop control system. The LS or LB commands set the frame sequence for the loop.
Refer to Chapter 2, Introduction, for more information about the loop control system.
