[MC_]CONFIRMED
The CONFIRMED verb replies to a confirmation request from the partner transaction program. It informs the partner transaction program that the local transaction program has not detected an error in the received data.
Because the transaction program issuing the confirmation request waits for a confirmation, the CONFIRMED verb synchronizes the processing of the two transaction programs.

} MC_CONFIRMED;Supplied Parameters
The transaction program supplies the following parameters to Personal Communications:
- opcode
- AP_B_CONFIRMED

AP_M_CONFIRMED
- opext
- AP_BASIC_CONVERSATION or AP_MAPPED_CONVERSATION. For nonblocking operation, this flag can be ORed together with AP_NON_BLOCKING.
- format
- Identifies the format of the VCB. Set this field to zero to specify the version of the VCB listed above.
- tp_id
- Identifier for the local transaction program. The value of this parameter was returned by the TP_STARTED verb in the invoking transaction program or by RECEIVE_ALLOCATE in the invoked transaction program.
- conv_id
- Conversation identifier. The value of this parameter was returned by the ALLOCATE verb in the invoking transaction processor or by RECEIVE_ALLOCATE in the invoked transaction processor.
Returned Parameters
If the verb executes successfully, Personal Communications returns the following parameter:
- primary_rc
- AP_OK
If the verb is nonblocking and has not completed, Personal Communications returns the following
parameters:
- primary_rc
- AP_OPERATION_INCOMPLETE
- opext
- AP_OPERATION_INCOMPLETE_FLAG
If the verb does not execute because of a parameter error, Personal Communications returns
the following parameters:
- primary_rc
- AP_PARAMETER_CHECK
- secondary_rc
- AP_BAD_CONV_ID
AP_BAD_TP_ID
AP_CONFIRMED_INVALID_FOR_FDX
If the conversation is in the wrong state when the transaction processor
issues this verb, Personal Communications returns the following parameters:
- primary_rc
- AP_STATE_CHECK
- secondary_rc
- AP_CONFIRMED_BAD_STATE
The conditions generating the following possible primary return codes (primary_rc) are described in APPC Common Return Codes.
- AP_TP_BUSY
- AP_UNEXPECTED_SYSTEM_ERROR
- AP_CONVERSATION_TYPE_MIXED
