Error Handling

Information about the outcome of your request is returned to your program in several different ways:

• The outcome of any request is indicated in register 15. In most cases, register 15 is all that needs to be checked.
• For debugging purposes, the following fields in the UIOCB contain additional information:
  • The UIOUCM2 field of the UIOCB contains CA IDMS/DC secondary error codes.
  • The UIOURTC field of the UIOCB contains VTAM return code and feedback information.
  • The UIOUSEI, UIOUSMI, and UIOUUSI fields of the UIOCB contain SNA sense codes.

The following table lists the sense codes CA IDMS/DC sends to the remote LU to inform the remote system of errors encountered in conversation processing. Sense codes are specified with a 4-byte hexadecimal value. CA IDMS/DC sends the following SNA sense codes to inform the remote system of errors encountered in conversation processing.
