IOPA001 The I/O routines

The I/O routines allow one to read, write or print the GEANT data structures. All GEANT I/O is handled though the ZEBRA system, which provides the following facilities:

• native and machine independent I/O to and from disk and tape devices;
• sequential and direct access I/O (from disk);

This allows, for example, to generate events on one machine, dump the data structures to a mass storage device, and then read them back for further processing on a different machine.

This section describes the various routines for I/O in GEANT. For a complete reference on the ZEBRA I/O system the user is referred to the ZEBRA documentation [,].
