     NAME       : HCPCAPBK
     DESCRIPTION: Connection Block for Advanced Printers
     DSECT      : CAPBK
     FUNCTION   : Represents an IUCV connection between a PSF
                  Virtual Machine and *SPL, and holds data and
                  workspace for process requests.
     LOCATED BY : SYSCAPQ - Anchor for system chain in SYSCM
                  VMDCAPQ - Anchor for user chain in VMDBK
     CREATED BY : CONNECT processing
     DELETED BY : SEVER processing
     SERIALIZED :
                  SYSCAPLK:  Protects the queue pointers and constant
                  path information.
                  CAPSYSNX, CAPUSRNX, CAPPATH, CAPNAME
                  CAPPLOCK:  Protects the variable path information:
                  CAPSTAT, CAPASPQ (including the ASPBK
                  pointers and contents), CAPRDOUT, and
                  all the SELECT fields.
