     NAME       : HCPSZVIN
     DESCRIPTION: SCSI Container SIC global block
     DSECT      : SZVIN
     FUNCTION   : The SCSI container CP code uses this block at
                  initialization time to save information for
                  later SIC calls.
                  It is pointed to from HCPSYSCM -> SYSSZBLK
