Each part of the full response code, Secondary and Primary, is 10 bytes in length with only the first 7 bytes currently being used. For Services which use a 2-byte response code in the parameter list, the full 20 byte response code is available in the Work-area following the first 42 bytes and the first 2 bytes are duplicated into the response code parameter.

The full response code has the following format:

EERRMMSxxxEERRMMSxxx
0.........10........
