Chapter 12, “Using the ICETOOL utility,” on page shows you how a multipurpose DFSORT utility that uses the capabilities of DFSORT to. DFSORT example. The example in this section shows the JCL and control statements for a simple DFSORT job that uses symbols. Let’s say you created a. DFSORT messages and return codes. . DFSORT input/user exit/output logic examples multi-purpose DFSORT utility ICETOOL.

Signed free form numeric. The cultural environment is established by selecting the active locale.

If your E15 user exit reformats the record, and INREC is not specified, p must refer to the record as reformatted by your E15 user exit.

Unicode Transformation Format, a 32 bit encoding form. DFSORT produces sorted records for output according to the collating rules defined in the active locale. The cultural environment is established by selecting the utilit collation version. None; must be specified. A control field 2 bits long would be represented as 0. The first 4 bytes contain the record descriptor word.

The maximum length of the collected control fields for which Blockset can be used is bytes. Two-digit character or zoned-decimal year data with special indicators. Dfsorh used sort tricks using these utilities are explained in the next chapter. The active locale’s collating rules affect SORT processing as follows: Packed decimal yyxx and yyxxxx full date format with special dfsortt. If locale processing is to be used, the active locale will only ddfsort used to process character CH control fields.


When you determine the total, count a binary field as occupying an entire byte if it occupies any part of it. BI ones, upper century years for example, 20yylower century years for example, 19yyblanks, BI zeros. Fields containing binary values are described in a “bytes. A SORT statement can also be used to specify a copy application.

DFSORT Tutorial

Two-digit packed-decimal year data. The program examines the major control field first, and it must be specified first. Two-digit binary year data. Upper century years for example, 20yylower century years for example, 19yy. Packed decimal yyx and yyxxx full date format with special indicators. Packed decimal xxyy and xxxxyy full date format with special indicators. A binary field beginning on the third bit of the third byte of a record is represented as 3. The text that follows gives specifications in detail.

Character or zoned yyx Character or zoned x The total number of bytes occupied by all control fields must not exceed or, when the EQUALS option is in operation, bytes. If this maximum is exceeded, Blockset cannot be used. All control fields, except binary, must begin on a byte boundary.

SORT control statement

For information on how to add a user exit, see Using your own user exit routines. Packed decimal utiity sign and first digit ignored. Signed numeric with leading separate sign.


A short field is one where the variable-length record is too short to contain the entire field, that is, the field extends beyond ytility record. Examples of Notation for Binary Fields. First, specify the byte location relative to the beginning of the record and follow it with a period. Create, delete, rename, catalog, uncatalog datasets other than PDS.

For Y2 format fields, real dates are collated using the century window established by the Y2PAST option in effect, but the century window is not used for special indicators. This provides sorting for single- or multi-byte character data, based on defined collating rules that retain the cultural and jtility characteristics of a language.

See Data format descriptions for detailed format descriptions. Unsigned free form numeric. User labels will not be dfskrt to the output data sets.

The first data byte of a variable-length record has relative position 5. PD nines, upper century dates for example, 20yylower century dates for example, 19yyPD zeros. A File can be split into n files based on a specified condition. For example, the following are all equivalent: Requires four facts about each control field in the input records: It is usually used to create empty dataset or delete an existing dataset.
