Learn More
DFSORT adds the ability to do faster and easier sorting, merging, copying, reporting, and analysis of your business information, as well as versatile data handling at the record, fixed position/length or variable position/length field, and bit level. Sort, merge, or copy data sets while including, excluding, or reformatting records. Collate and compare data according to your national and cultural needs by using DFSORT's National Language Support. Add timestamps to records, perform date field conversions and arithmetic, include or omit records based on today's date, a past date or a future date, and convert SMF, TOD, and ETOD date and time values to readable form. Join and match records from different data sets in various ways.
DFSORT includes the high-performance ICEGENER facility, the versatile ICETOOL utility, Symbols, and multiple output capabilities with the powerful OUTFIL feature. Analyze data and produce detailed reports by using the ICETOOL utility or the OUTFIL function. In addition, OUTFIL allows you to create different views of the data and different reports with a single pass over the data. Use symbols for fields and constants in DFSORT and ICETOOL statements.
DFSORT is designed to optimize the efficiency and speed with which operations are completed through synergy with processor, device, and system features (for example, memory objects, Hiperspace, data space, striping, compression, extended addressing, DASD and tape device architecture, processor memory, processor cache, and so on) and other products (for example, The SAS System, COBOL, PL/I, IDCAMS BLDINDEX, and so on).
DFSORT together with DFSMS and RACF, form the strategic product base for the evolving system-managed storage environment.
