E16 return codes

Your E16 routine must pass a return code to DFSORT. Following are the return codes for the E16 user exit:

0: Sort Current Records Only: If you want DFSORT to continue with only that part of the input data set it estimates it can handle, return with a return code of 0 (zero). Message ICE054I contains the number of records with which sort is continuing. You can sort the remainder of the data set on one or more subsequent runs, using SKIPREC to skip over the records already sorted. Then you can merge the sort outputs to complete the operation.
4: Try to Sort Additional Records: If you want DFSORT to continue with all of the input data set, return with a return code of 4. If tapes are used, enough space might be available for DFSORT to complete processing. If enough space is not available, DFSORT generates a message and terminates. Refer to Exceeding tape work space capacity.
8: Terminate DFSORT: If you want DFSORT to terminate, return with a return code of 8. DFSORT then returns to its calling program or to the system with a return code of 16.
