DFS070 diagnostic message

This is an example of the DFS070 diagnostic message. 

DFS070 UNABLE TO ROUTE MESSAGE RSN=0104

The RSN code identifies the module that issued the message (01 = DFSICIO0) and the reason for the error (04 = Prefix buffer length is too large).

In this case DFSICIO0 called the message generator (DFSCLMR0) with R1 = 00680046. 
Where x'00680046' = module identifier, reason code,message key
                         x'0068' = 0104 (decimal)
                                    01 = Module that issued message = DFSICIO0
                                    04 = Prefix buffer length is too large
                         x'0046  = 70 (decimal) = DFS070 MESSAGE KEY

The following table shows:

  • The label used for the module identifier
  • The identifier
  • The module function or name

The labels shown in the following table can be used to scan the module source code to locate where the message was issued from.
