The structure and fields of the request message headers are described
in this section. These headers, along with the application data, comprise
the request message that is sent by the service requester in a COMMAREA.
The following headers are described:
DFHMAH header structure
The request message header DFHMAH describes the structure of the
application data. It is mapped by copybook DFHMAHV, which is located in the
library SCIZMAC.
DFHMAH field definitions
The following definitions describe the content of each field in
the DFHMAH message header.
DFHMAH2 header structure
The request message header DFHMAH2 describes the structure of the
application data for a passthrough request message. It is mapped by copybook
DFHMAH2V, which is located in the library SCIZMAC.
DFHMAH2 field definitions
The following definitions describe the content of each field in
the CICS Service Flow Runtime passthrough
message header (DFHMAH2).
CIA-SCREEN-HEADER header structure
When the runtime processing is running in passthrough mode, the
CIA-SCREEN-HEADER structure is required. It must immediately follow the DFHMAH2
header structure. To view the passthrough screen header, see copybook DFHMALSH
in the SCIZMAC library.
CIA-SCREEN-HEADER field definitions
The following definitions describe the content of each field in
the CICS Service Flow Runtime passthrough
Screen header (CIA-SCREEN-HEADER).
CIA-MAP-HEADER header structure
When the server runtime processing is running in passthrough mode,
the CIA-MAP-HEADER structure is required. It must immediately follow the CIA-SCREEN-HEADER
structure. To view the passthrough map header, see copybook DFHMALMH in the
SCIZMAC library.
CIA-MAP-HEADER field definitions
The following definitions describe the content of each field in
the CICS Service Flow Runtime passthrough
map header (CIA-MAP-HEADER).
