E32 return codes

Your E32 routine must pass a return code to DFSORT. Following are the return codes for the E32 user exit:

8: End of input for requested file: DFSORT continues to return control to the user routine until it receives a return code of 8 for every input file. After that, the user exit is not used again during the DFSORT application. You need not place an address in the second field of the parameter list when you return with a return code of 8.
12: Insert Record: To add a record from the requested input file, place the address of the next record in the parameter list and return to DFSORT with a return code of 12. DFSORT keeps returning to your routine until you pass a return code of 8 for every input file.
16: Terminate DFSORT: If you want to terminate DFSORT, return with a code of 16. DFSORT then returns to its calling program with a return code of 16.
