ISSUE SIGNAL

Requests a change of direction from sending transaction on an advanced program-to-program communications (APPC) mapped conversation.
An APPC conversation allows a program to send data to, and receive data from, a program that is running in a remote system.
Programming that uses APPC conversations is called Distributed Transaction Programming (DTP).
For guidance information about DTP, refer to the TXSeries for Multiplatforms Intercommunication Guide.)

Sintaxe:

Descrição:

ISSUE SIGNAL raises the SIGNAL condition on the next SEND, RECEIVE, or CONVERSE command that is executed in the remote transaction.

For COBOL programs only, a previously executed HANDLE CONDITION command for this condition can be used either to take some action, or to ignore the request.

Opção:

    CONVID(name)
  • Identifies the conversation to which the command relates.
  • The four-byte name identifies either the token that is returned by a previously executed ALLOCATE command in the EIBRSRCE field of the EXEC Interface Block (EIB), or the token that represents the principal facility (that was returned by a previously executed ASSIGN command).
  • If this option is omitted, the principal facility is assumed.
    STATE(cvda)
  • Gets the state of the current conversation.

Condições:

    INVREQ
  • Occurs for the following conditions, depending on the options that are specified on the ISSUE SIGNAL command:
    • The CONVID option is omitted and the principal facility is not an APPC conversation.
    • A remotely linked-to program attempted to execute an ISSUE SIGNAL command that refers to the principal facility.
  • Ação pré-definida: Terminates the task abnormally.
    NOTALLOC
  • Occurs if the specified CONVID value does not relate to a conversation that is owned by the application.
  • Ação pré-definida: Terminates the task abnormally.
    TERMERR
  • Occurs if a session-related error occurs. Any subsequent action on that conversation other than a FREE command causes an ATCV abend.
  • Ação pré-definida: Terminates the task abnormally (with abend code ATNI).
