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:
