     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.
                  HCPIID   - Create a real device RDEV
                  HCPLSOCR - Create a logical device RDEV
                  HCPSRD   - Create a real device RDEV
                  HCPVCTCN - Create a SNA device RDEV
                  HCPZCO   - Create a real device RDEV
                  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.
