    Explanation
      An application program has attempted to perform a function not supported by a terminal or system.

      Possible errors are:

      
        
          
            SIGNAL not supported.

          A DFHTC TYPE=SIGNAL request with the WAIT=YES option was issued to a VTAM logical unit that CICS does not support for the receipt of the SIGNAL indicator.

        

        
          
            WRITE STRUCTURED FIELD not supported.

          This write may have been attempted as a result of a SEND command with the STRFIELD keyword to a device that does not support this function.

        

        
          
            APPC mapped conversation not supported.

          The application has attempted to perform a normal terminal control command on a session that is in use for an APPC unmapped conversation. (Only EXEC CICS GDS commands are permitted.)

        

      

    

    System action
      The transaction is abnormally terminated with a CICS transaction dump.

    

    User response
      Correct the application program.
