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.

SORT control statement
Signed numeric with leading separate sign. Signed numeric with leading utilify sign. The minor control fields are specified following the major control field.
The SORT control statement must be used when a sorting application is performed; this statement describes the control fields in the input records on which the program sorts. For example, the following are all equivalent: 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. Used to copy selected parts of a JCL. The total number of bytes occupied by all control fields must not exceed or, when the EQUALS option is in operation, bytes.
Remember that the first high-order bit of a byte is bit 0 not bit 1 ; the remaining bits are numbered 1 through 7. Examples of Notation for Binary Fields. Specify E if you include an E61 user exit to modify control ufility before the program sorts them.
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. All floating-point data must be normalized before the program can collate it properly. Usually used to manage VSAM datasets. First, specify the byte location relative to the beginning of the record and follow it with a period. The maximum length of the collected control fields for which Blockset can be used is bytes.
For example, a binary field that begins on byte 2. Lower century years for example, 19yyupper century years for example, 20yy. For information on how to add a user exit, see Using your own user exit routines. Packed decimal yyx and yyxxx full date format dfsor special indicators. This provides sorting for single- or multi-byte character data, based on defined collating rules that retain dsfort cultural and local characteristics of a language. Signed numeric with trailing separate sign.
JCL Utility Programs
A SORT statement can also be used to specify a copy application. Character with alternate collating sequence. Input and output datasets can be defined using user defined DD names. Unsigned free form numeric. Character or zoned utllity BI ones, upper century years for example, 20yylower century years for example, 19yyblanks, Utiljty zeros.
It gives best utilization of system resources and efficient operation in bit and bit address spaces. Character or zoned x When you determine the total, count a binary field as occupying an entire byte if it occupies any part of it.
Upper century years for example, 20yylower utilty years for example, 19yy. It can compare two or more files on specified field s and create one utilitu more output files like file with matching records, file with non-matching records, etc. Requires four facts about each control field in the input records: Other examples of this notation are shown in Figure PD nines, upper century dates for example, 20yylower century dates for example, 19yyPD zeros.
Unicode Transformation Format, a 32 bit encoding form. A control field 2 bits long would be represented as 0.
Unicode Transformation Format, a 16 bit encoding dfsirt. The active collation version rules affects SORT processing as follows: Two-digit character or zoned-decimal year data.
The text that follows gives specifications in detail. The first byte of a floating-point field is interpreted as a signed exponent; the rest of the field is interpreted as the fraction. The first 4 bytes contain the record descriptor word. For example, a file containing names of employees can be split into 26 files, each containing the names starting with A, B, C and so on.
A File can be split into n files based on a specified condition. The cultural environment is established by selecting the active collation version. Packed decimal yyxx and yyxxxx full date format with special indicators.
User-defined data type requires an EFS program. Two-digit packed-decimal year data. A few of them are listed below with their functionality:.
