NAME : HCPBCPRG
DESCRIPTION: CHANNEL PROGRAM DSECT BLOCK
DSECT : RDLBCST
FUNCTION : TO MAP THE COMMON CHANNEL PROGRAMS USED IN CP.
LOCATED BY : THE FOLLOWING MACROS USE THE HCPBCPRG DSECTS:
BLDCPRAC MACRO - READ CKD ALLOCATION MAP
BLDCPRAE MACRO - READ ECKD ALLOCATION MAP
BLDCPRLC MACRO - READ CKD DASD LABEL
BLDCPRLE MACRO - READ ECKD DASD LABEL
BLDCPWAC MACRO - WRITE CKD ALLOCATION MAP
BLDCPWAE MACRO - WRITE ECKD ALLOCATION MAP
BLDCPWLC MACRO - WRITE CKD DASD LABEL
BLDCPWLE MACRO - WRITE ECKD DASD LABEL
BLDCPRAF MACRO - READ FBA ALLOCATION MAP
BLDCPRLF MACRO - READ FBA DASD LABEL
BLDCPWAF MACRO - WRITE FBA ALLOCATION MAP
BLDCPWLF MACRO - WRITE FBA DASD LABEL
BLDCPSID MACRO - SENSE ID (DASD)
BLDCPUNL MACRO - UNLOAD BUFFER (DASD)
BLDCPSCD MACRO - Perform Subsystem Function (DASD)
BLDCPSCT MACRO - Perform Subsystem Function (TAPE)
CREATED BY : INDIVIDUAL DSECTS ARE CREATED BY THE SYSTEM WHEN THE
CHANNEL PROGRAM IS NEEDED.
DELETED BY : DSECTS ARE DELETED AFTER THE I/O IS COMPLETE.
