type o RECORD Keeps records intact while sorting and produces an output file consisting of complete records. Record is the default sorting process. High-performance Sort/Merge: The high-performance Sort/Merge utility currently supports only the record process. o TAG Sorts only the keys and then rereads the input file to produce an output file consisting of complete records. o ADDRESS Sorts only the keys and produces an output file that is an index of record addresses in binary format. The index must be submitted to a program for further processing. o INDEX Creates an output file containing both RFAs and key fields, plus a file number when sorting multiple files. The format of these key fields is the same as in the input files. If the program needs key field content for a decision during future processing, select index sort rather than address sort.
