NAME : CPRB DESCRIPTION: Connectivity Programming Request Block DSECT : CPRBxxxx FUNCTION : OBTAIN AND PARTIALLY INITIALIZE CPRB, OR CREATE DSECT INVOCATION : LABEL CPRB DSECT=YES/NO (LABEL) IS AN OPTIONAL LABEL (DSECT) SPECIFIES WHETHER TO GENERATE A DSECT (YES) OR OBTAIN A CPRB (NO)-- YES IS DEFAULT Operation : IF SPECIFIED WITH DSECT=NO, CPRB ATTEMPTS TO OBTAIN STORAGE FOR A CPRB AND, IF SUCCESSFUL, FILLS IN THE CONSTANT FIELDS OF IT. REG 1 IS SET TO THE ADDRESS OF THE RESULTING CPRB. IF DSECT=YES IS SPECIFIED OR DEFAULTS, A DSECT IS GENERATED DEFINING THE FIELDS OF THE CPRB. The Connectivity Programming Request Block contains information passed by a requester to the SRPI on entry to a server and information passed back from the server to the requester. The server can set some of the fields of the CPRB, and the system uses other fields, a path, and device or both. A buffer may be specified for the OPEN or QUERY functions, and the information will be stored in this buffer by the console function. CPRB is called by the CPRB macro.CPRB0001 Control Block Content
