The I/O routines permit to read, write or print the GEANT3 data structures. When I/O with tapes is performed, the data structures can be handled in native mode or in machine independent format, using either the FZ package of 5 ZEBRA (for GGET, GSAVE) or the RZ package (for GRGET, GRSAVE).

Events can be generated on one type of machine, for example full detector simulation, and the data produced can be analyzed on a different machine.

The data structures written to tape or disk can be read either in whole or in part.
