 NAME       : HCPRDCBK
 DESCRIPTION: Real Device Characteristics Block
 DSECT      : RDCBK
 FUNCTION   : The Real Device Characteristics Block contains
              DEVICE/CONTROL UNIT information.  This data is
              divided into two parts:
              - static device information.
              - 64 bytes of information returned from a
              RDC (Read Device Characteristics) CCW.
 LOCATED BY : RDEVRDCA Field of the RDEV.
              SYSRDCA  Field of the SYSCM
              - Address of the first RDCBK entry
 CREATED BY : RDCBK'S are dynamic and in part are created by the
              device specific initialization modules.
              RDCBK'S also acquire their data from a Read Device
              Characteristic CCW during device initialization.
 DELETED BY : RDCBK'S are created at Initialization or the
              Vary Online command and are never deleted.
 SERIALIZED : RDEV Lock
 COMMENTS   : When using this block for FBA DASD, the
              first 8 bytes should not be included
              since the RDC CCW doesn't return this
              information.  Therefore to use this
              DSECT when issuing the RDC CCW, the data
              returned must be placed starting at
              RDCFBARE.
              Notes      : Field RDCFBARE is defined
              starting at location RDCOPER (RDCFEAT+2).
