GTRIG User routine to generate or read the kinematic GUKINE User routine to handle the tracking of the initial kinematics GUTREV User routine to perform digitisation GUDIGI User routine called at the end of each event GUOUT Figure 5: Flow of the GRUN routine. CALL GTRIG Steering routine to process one event (trigger). A schematic description of the routine is shown in fig. 5. Default routines provided by GEANT are dummy.

Geant 3.16 GEANT User’s Guide BASE280 Origin : M.Maire Submitted: 14.12.93 Revision : Revised: 14.12.93 Documentation : Storing and retrieving JRUNG and JHEAD information CALL GSRUNG (NUBUF,UBUF,IADR*) NUBUF UBUF IADR (INTEGER) number of user words; (REAL) array of user words; (INTEGER) position where information is stored in the user bank of the JRUNG structure. This routine stores the first NUBUF words of array BUF in the user bank attached to the structure JRUNG (see [BASE299]), starting at location IADR+1. On exit IADR is set to IADR+NUBUF, allowing subsequent filling. This allows effectively to add information to the current JRUNG bank, whether or not it has already an user buffer. CALL GFRUNG (NWRUNG*,IRUNG*,NUBUF*,UBUF*) NWRUNG IRUNG NUBUF UBUF (INTEGER) number of words in JRUNG bank; (REAL) content of JRUNG bank; (INTEGER) number of user words; (REAL) array of user words; This routine retrieves the content of the JRUNG bank and of the user information added, if any. CALL GPRUNG This routine prints the content of the JRUNG bank and of the user information added, if any. CALL GSHEAD (NUBUF,UBUF,IADR*) NUBUF UBUF IADR (INTEGER) number of user words; (REAL) array of user words; (INTEGER) position where information is stored in the user bank of the JHEAD structure. This routine stores the first NUBUF words of array BUF in the user bank attached to the structure JHEAD (see [BASE299]), starting at location IADR+1. On exit IADR is set to IADR+NUBUF, allowing subsequent filling. This allows effectively to add information to the current JHEAD bank, whether or not it has already an user buffer. CALL GFHEAD (NWHEAD*,IHEAD*,NUBUF*,UBUF*) NWHEAD IHEAD NUBUF UBUF (INTEGER) number of words in JHEAD bank; (REAL) content of JHEAD bank; (INTEGER) number of user words; (REAL) array of user words; This routine retrieves the content of the JHEAD bank and of the user information added, if any.
