provides uniform random numbers. All other random number routines are linked to this one. This routine is stored in the BASES library( libbases.a).
performs an initialization for DRN(ISEED). This is also stored in libbases.a.
reads input data cards from grape.cards.
provides masses/widths of particles and the QED coupling constant.
can be modified by users to access the information on generated events. User initialization/termination procedures are also put in this routine.
