Using the ICETOOL utility

The active collation version rules affects SORT processing as follows: Packed decimal xxyy and xxxxyy full date format with special indicators. Signed numeric with leading overpunch sign. This provides sorting for single- or multi-byte character data, based on defined collating rules that retain the cultural and uti,ity characteristics of a language.

You can use an E15 or E61 user exit to do this during processing. The text ugility follows gives specifications in detail. Signed numeric with trailing overpunch sign.


All fields must be completely contained within the first bytes of the record. However, the maximum length can be less than for various situations, such as the use of certain formats for example, PDthe EQUALS option, and so on.

This provides sorting for single-or multi-byte character data based on defined collating version rules that retain the cultural and local characteristics of a language. Character with alternate collating sequence. The active locale’s collating rules affect SORT processing as follows: User-defined data type requires an EFS program. A few of them are listed below with their functionality:. The program examines the major control field first, and it must be specified first.

The maximum length of the collected control fields for which Blockset can be used is bytes. Two-digit character or zoned-decimal year data. Then, specify the bit location relative to the beginning of that byte.

SORT control statement

Signed numeric with optional leading floating sign. Upper century years for example, 20yylower century years for example, 19yy.

Packed decimal xyy and xxxyy full date format with special indicators. Requires four facts about each control field in the input records: Remember that the first high-order bit of a byte is bit 0 not bit 1 ; the remaining bits are numbered 1 through 7. Unsigned free form numeric. Character or zoned yyx Character or zoned x Unicode Transformation Format, a 32 bit encoding form. It is usually used to create empty dataset or delete an existing dataset. Create, delete, rename, catalog, uncatalog datasets other than PDS.


Utility programs are pre-written programs, widely used in mainframes by system programmers and application developers to achieve day-to-day requirements, organising and maintaining data.

DFSORT example

A File can be split into n files based on a specified condition. DFSORT produces sorted records for output according dffsort the collating version rules defined in the active collation version. PD nines, upper century dates for example, 20yylower century dates for example, 19yyPD zeros.

Usually used to manage VSAM datasets.
