DBCWK Prolog
NAME : HCPDBCWK
DESCRIPTION: DASD Block I/O work block
DSECT : DBCWK
FUNCTION : Contains information specific to DASD block
I/O requests. It is basically a work area
for HCPDBC and it is also now used as the control
block to represent the current state of a
particular Diagnose 250 or *BLOCKIO (request).
(The SNDBK and BRQBK used to fulfill these
roles, any fields in those control blocks
now reside here).
Since a number fields are specific to the particular
i/o request, there is an overlay portion of this control
block at label DBCSPECL. The overlays are defined in
here and there is an overlay for each type of i/o.
LOCATED BY : This is pointed to by R13 in all of the
block i/o handlers (HCPBIM, HCPBIR, HCPDGB
HCPBID, HCPDGD, HCPDBC and HCPDBD).
CREATED BY : HCPDGB (Diag A4 handling)
HCPBIM (*BLOCKIO handling)
HCPBID (Diag 250 handling)
HCPDGD (Diag 18 handling)
DELETED BY : HCPDGB (Diag A4 handling)
HCPBIM (*BLOCKIO handling)
HCPBID or HCPBIR (Diag 250 handling)
HCPDGD (Diag 18 handling)
COMMENTS : The DBCWK area contains one BPLBK (DBCSINGL) and one
IPARML Reply (DBCPARML). If the size of either of
these control blocks changes, then DBCSINGL and
DBCPARML should be updated accordingly.
