BASE200 Steering routines for event processing

CALL GRUN Main routine to control a run of events. The following flow chart is only valid for the batch execution mode. For interactive applications, see section XINT. A schematic description of the routine is shown in fig. .

Figure: Flow of the GRUN routine.

CALL GTRIGI Initialisation routine for event processing:

• resets to 0 the flag IEOTRI in /GCFLAG/ and the counters NTRACK and NVERTX in /GCNUM/;
• sets the debug flag IDEBUG in /GCFLAG/ to the value required for the current event;
• creates a default header bank JHEAD for current event [BASE299];
• prints the sequence number, the event number and the random number generator seeds, under control of the flag ITEST (data record DEBU).

CALL GTRIG

Steering routine to process one event (trigger). A schematic description of the routine is shown in fig. .

Figure: Flow of the GRUN routine.

Default routines provided by GEANT are dummy.

CALL GTRIGC The event division IXDIV is cleared. The space used by the current event may be used by the next one.
