AAAREADME.TXT for [MIVAXLUG.SIDPARSE]

    The SID (System IDentification) register is comprised of several fields.
    The  format  of  the  SID  varies  from  one  class of VAX processors to
    another.  Not all processor classes have serial number fields.   In  ALL
    cases, the left most byte of information is the CPU class number.

    The  SIDPARSE command procedure takes apart a SID value and displays the
    relevent  fields.  A SID can  be supplied or, if  <cr>  is entered,  the
    current system's SID is obtained and used.
