Appendix I. TPF Sense Code Processing

Every SNA command sent by the TPF system has a corresponding response handler that performs sense error handling internally or passes control to the SSCP negative response handler.

The response handler handles a negative response if it is to be treated as a positive response. Generally a negative response to the last command to flow during session deactivation is treated as positive because, whether the response is positive or negative, everything should be cleaned up at this time. Examples of commands that can be the last commands to flow are CDSESSEND, CDTERM, DACTCDRM, DACTPU and UNBIND.

The actions that can be taken by the negative response handler are:

Table 26 shows the action taken based on the sense code. The default action for any sense code not listed in this table is CLNUP, a message, and the 511 SNAPC dump.
