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 model branches the specified block
<branchToBlock>
The block number of the trigger model block to execute when the specified event
occurs
Details
The branch-on-event 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.
If you set the branch event to none, an error is generated when you run the trigger model.
The f oll owing table shows the constants for the events.
