*  is loaded into the 5th word of the Crate Header.  The Revision       *
*  Number does not change from one event to the next.  It appears in    *
*  the Crate Header of each data block sent out with this program.      *
*  The Revision Number specifies the revision of the: VME CPU Program,  *
*  the COMINT PROM's, the Lookup System revision, and the L1 Trigger    *
*  hardware revision.                                                   *
