| x"FA01" | Initiates the sort operation. If the number of USING files is other than zero, the sort starts immediately, using the specified files as input. If the number of GIVING files is other than zero, the sort operation processes the GIVING files before returning control to the calling program. |
| x"FA40" | Initiates the merge operation. For this operation the number of USING files must be other than zero. It is assumed that the records in each of the USING files are already sorted. |
| x"FAF3" | Releases a record to the sort operation. You should use this function only when the number of USING files is zero. |
| x"FA10" | Terminates the input stage of the sort operation. You should use this function only when the number of USING files is zero. It indicates that no more release operations are to be performed. If the number of GIVING files is other than zero, the sort operation writes the sorted data to the GIVING file and terminates. |
| x"FAF5" | Returns a record from the sort or merge operation. You should use this function only when the number of GIVING files is zero. |
| x"FA88" | Terminates the sort or merge operation, releasing all memory allocated for the operation and deleting any temporary files. You should use this function only when the number of GIVING files is zero. It indicates that no more return operations are to be performed. |
