Usage
:TRIGger:BLOCk:BRANch:EVENt <blockNumber>, <event>, <branchToBlock>
<blockNumber>
The sequence of the block in the trigger model
<event>
The event that must occur before the trigger block will act
<branchToBlock>
The block number of the trigger model block to execute when the specified event
occurs
Details
The branch-on-event building block goes to a branching block after a specified trigger event occurs. If the trigger
event has not yet occurred when the trigger model reaches the branch-on-event block, the trigger model
continues to execute the blocks in the normal sequence. After the trigger event occurs, the next time the trigger
model reaches the branch-on-event block, it goes to the branching block.
The event can be one of the events shown in the following table.

Example
:TRIG:BLOC:BRAN:EVEN 6, DISP, 2
When the trigger model reaches this block, if the front-panel TRIGGER key has been pressed, the trigger
model returns to block 2. If the TRIGGER key has not been pressed, the trigger model continues to block 7
(the next block in the trigger model).
