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. .

Two-digit character or zoned-decimal year data.
Using the ICETOOL utility
Signed numeric with trailing separate sign. Usually, this is not recommended in view of performance for large files.
Unicode Transformation Format, a 16 bit encoding form. PD nines, upper century dates for example, 20yylower century dates for example, 19yyPD zeros. The options available on the Uti,ity statement can be specified in other sources as well. The maximum length of the collected control fields for which Blockset can be used is bytes. The active locale’s collating rules affect SORT processing as follows: User labels will not be copied to the output data sets. utulity
Character or zoned yyx First, specify the byte location relative to the beginning of the record and uyility it with a period. You can use an E15 or E61 user exit to do this during processing.

User-defined data type requires an EFS program. BI ones, upper century years for utilitu, 20yylower century years for example, 19yyblanks, BI zeros. 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. Two-digit character or zoned-decimal year data with special indicators. When the beginning of a binary field falls on a byte boundary say, for example, on the fourth byteyou can write it in one of three ways: Unicode Transformation Format, a 32 bit encoding form.
Using the ICETOOL utility
Two-digit packed-decimal year data. BI zeros, blanks, lower century years for example, 19yyupper century years for example, 20yyBI ones. A few of them are listed below with their functionality:.
A binary field beginning on the third bit of the third byte of a record is represented as 3. Other examples of this notation are shown in Figure These utility programs need to be used with appropriate DD statements in a JCL in order to achieve the specified functionality.
Character or zoned x Signed numeric with optional dfsoet floating sign. PD zeros, lower century dates for example, 19yyupper century dates for example, 20yyPD nines. All fields must be completely contained within the first bytes of the record.
All control fields, except binary, must begin on a byte boundary. Packed decimal yyx and yyxxx full date format with special indicators. Packed decimal with sign and first digit ignored. The first data byte of a fixed-length record has relative position 1.
Signed numeric with leading overpunch sign. The active collation version rules affects SORT processing as follows: A control field 2 dfwort long would be represented as 0. For example, a binary field that begins on byte 2. 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.
Upper century years for example, 20yylower century years for example, 19yy.
A File can be split into n files based on a specified condition. Packed decimal yyxx and yyxxxx full date format with special indicators. If locale processing is to be used, the active locale will only be used to process character CH control fields.
Unicode Transformation Format, a 8 bit encoding form. Create, delete, rename, catalog, uncatalog datasets other than PDS. 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. All floating-point data must be normalized before the utiliyy can collate it properly. A short field is one where the variable-length record is too short to contain the entire field, that is, the field extends beyond the record.
Remember that the first high-order bit of a byte is bit 0 not bit 1 ; the remaining bits utilityy numbered 1 through 7. See Data format descriptions for detailed format descriptions.
None; must be specified.
