DFSORT, ICETOOL upgraded in 2008

DFSORT is IBM's high performance sort, merge, copy, analysis and reporting product. DFSORT is an optional feature of z/OS.

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 includes the high-performance ICEGENER facility, the versatile ICETOOL utility, Symbols, and multiple output capability with the powerful OUTFIL feature.

z/OS DFSORT V1R5 PTF UK90013, which was first made available in July, 2008, provides important enhancements to DFSORT and DFSORT's ICETOOL. Below is the list of few newly enhanced functions:

• Find and Replace (FINDREP).
• Group Operations(WHEN=GROUP).
• Sorting data between headers and trailers (DATASORT).
• Keeping or Removing the first n records (SUBSET).
• Selecting the first n duplicate records (SELECT with FIRST(n) and FIRSTDUP(n)).
• Splicing with non-blank fields (SPLICE with WITHANY).
• Displaying and Writing counts (DISPLAY with COUNT, ect).
• Reports with multiple and multipart titles (DISPLAY and OCCUR with TITLE, etc).
• Reports without carriage control characters (DISPLAY and OCCUR with NOCC).
• Additional defaults (BLKSIZE for DUMMY, SKIP=0L for SECTIONS, etc).
• Easier migration from other sort products, and more.

We will look into the above functions in detail in our next post.
