NAME : HCPGSXBK DESCRIPTION: Cross system communication block DSECT : GSXBK FUNCTION : Maps the GSDDATA field in the HCPGSDBK for use by CSE in cross system communication. This DSECT is used to pass the user ID and other pertinent information about the user who issued a CP command sent to this system from another system in this CSE complex. The control block is created when a QITEM is received representing a CP command that is to be executed on this system. The CP command processors, such as HCPCSC for the TRANSFER command, and HCPTHI for the INDICATE command, use the information in this control block in lieu of the VMDBK. HCPQCNWT uses this information to determine to which system responses should be sent. LOCATED BY : (Overlay of) GSDDATA field of HCPGSDBK CREATED BY : HCPXCC DELETED BY : HCPXCC
