     TRIGGER Control Structure

     The TRIGGER is used to control the scheduling of a data
     path.  The trigger takes two input connections.  The first
     is the input connection that provides the data flow for the
     output.  The second is the procedure or other network which
     will will determine the timing for the trigger.  The trigger
     will not allow the input to be scheduled until the second
     network has finished executing.  When the second network has
     finished executing, the trigger glyph will be executed, the
     input connection data is then propagated to the output
     filename.  The rest of the network connected to the glyph's
     output connection will then be active for scheduling and
     dispatching.

     Special Thanks To:

     TRIGGER glyph to cantata.
