Use the TPPCC general macro with the CONFIRMED verb specified to send a
confirmation reply to the remote transaction program. This allows the 2
programs to synchronize their processing. The local TPF transaction
program can issue this verb when it receives a confirmation request from the
remote transaction program. See the WHATRCV parameter of the RECEIVE
verb (see TPPCC RECEIVE).
Format
- label
- A symbolic name can be assigned to the macro statement.
- CONFIRMED
- Directs the TPPCC macro to perform the CONFIRMED verb function.
- RESID
- Specifies the symbolic name of a field or a register that points to a
field. This is a 4-byte field in which the resource ID is
supplied. This resource ID must be the one assigned on the initial
ALLOCATE for this conversation or one that was assigned by an incoming
ATTACH.
- RCODE
- Specifies the symbolic name of a field or a register that points to a
field. This field is a 6-byte field in which the return code is
placed. The return code consists of a 2-byte primary return code
followed by a 4-byte secondary return code. The actual values returned
are listed in Return Conditions.
Entry Requirements
- The conversation must be in one of the following states:
received-confirm
received-confirm-send
received-confirm-deallocate
- See Entry Requirements for the entry requirements relating to the TPPCC macro in
general.
Return Conditions
- The results of the verb are indicated by the value returned in
RCODE. The valid return codes are listed in the following section,
"Return Codes".
- See Return Conditions for the return conditions relating to the TPPCC macro in
general.
- The following table contains a list of the primary and secondary return
codes that can be returned to the program that issued the CONFIRMED
verb. A complete list of return codes and their definitions can be
found in Table 11 and in Table 12.

Programming Considerations
- If you specify a register for a keyword value, the register must be
enclosed in parentheses and in the range R1-R7.
- The value supplied in RESID must be the resource ID returned by the
ALLOCATE verb or one that was assigned by an incoming ATTACH.
- A transaction program can issue this verb only as a reply to a
confirmation request; the verb cannot be issued at any other time.
Transaction programs can use this verb for various application-level
functions. For example, the remote program can send data followed by a
confirmation request. When the local program receives the confirmation
request, it can issue this verb as an indication that it received and
processed the data without error.
- See Programming Considerations for the programming considerations relating to the TPPCC
macro in general.
