  SYSGEN>  SHARE MPM1 SHR_MEM_1/INITIALIZE -
  SYSGEN>  /GBLSECTIONS=128/MAILBOXES=64/CEFCLUSTERS=0

      This command initializes a multiport memory unit with defaults
      on all but the gbl, mail, and cef parameters. In this example,
      assume that the number of the multiport memory unit as it
      appears on the front panel is 1, and the unit name is SHR_
      MEM_1.
