     NAME       : HCPRDEV
     DESCRIPTION: REAL DEVICE CONTROL BLOCK
     DSECT      : RDEV
     FUNCTION   : THE REAL DEVICE BLOCK IS USED TO MANAGE THE REAL
                  DEVICE.
     LOCATED BY : HCPRIOIX is the anchor field for the RDEV radix tree
                  structure for devices in the default subchannel set.
                  HCPRIOIA is the anchor field for the RDEV radix tree
                  structure for devices in the alternate subchannel set.

     CREATED BY : Real device RDEVs are created in HCPRIO by the
                  sysgen process.
                  Real device RDEVs are created during SET RDEVICE
                  command, machine check CRW processing, or system
                  initialization.
                  RDEVs are created for logical or SNA devices.

                  HCPZRP   - Create a real device RDEV
     DELETED BY : Real device RDEVs created in HCPRIO by the sysgen
                  process are static and are never deleted.
                  Real device RDEVs created during SET RDEVICE
                  command, machine check CRW processing, or system
                  initialization may be deleted, but only early in
                  system initialization before anybody can start
                  using them.
                  RDEVs created for logical or SNA device are dynamic
                  and are deleted when no longer required.
