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.

User labels will not be copied to the output data sets. Packed decimal xyy and xxxyy full date format with special indicators. The cultural environment is established by selecting the active locale. The first 4 bytes contain the record descriptor utiliyy.
Signed numeric with trailing separate sign.
Packed decimal xxyy and xxxxyy full date format with special indicators. 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. Signed free form numeric. The program examines the major control field first, and it must be specified first.
Fields containing binary values are described in dfort “bytes. Upper century years for example, 20yylower century years for example, 19yy. This provides sorting for single- or multi-byte character data, based on defined collating rules that retain the cultural and local characteristics of a language. All fields must be completely contained within the first bytes of the record.
PD nines, upper century dates for example, 20yylower century dates for example, 19yyPD zeros. You can use an E15 or E61 user exit to do this during processing. If your E15 user exit reformats the record, and INREC is not specified, p must refer to the record as reformatted by your E15 utllity exit.
Then, specify the bit location relative to the beginning of that byte. The minor control fields are specified following the major control field. DFSORT produces sorted records for output according to the collating rules defined in the active locale.
Packed decimal yyxx and yyxxxx full date utiliry with special indicators. The options available on the SORT statement can be specified in other sources as well.
Two-digit packed-decimal year data. If this maximum is exceeded, Blockset cannot utiility used. Frequently used sort tricks using these utilities are explained in the next chapter.
Remember that dfsot first high-order bit of a byte is bit 0 not bit 1 ; the remaining bits are numbered 1 through 7. Thus the Y2 formats will collate real dates and special indicators as follows: Two-digit character or zoned-decimal year data. 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. Signed numeric with leading overpunch sign.
A File can be split into n files based on a specified condition. When you determine the dtsort, count a binary field as occupying an entire byte if it occupies any part of it. Signed numeric with trailing overpunch sign. However, the maximum length can be utiilty than for various situations, such as the use of certain formats for example, PD ugility, the EQUALS option, and so on.
BI ones, upper century years for example, 20yylower century years for example, 19yyblanks, BI zeros. The first data byte of a variable-length record has relative position 5. Unsigned free form numeric.
Signed numeric with leading separate sign. Character or zoned yyx Packed decimal with sign and first digit ignored. None; must be specified. Character with alternate collating sequence. Character or zoned x Usually used to manage VSAM datasets. The active locale’s collating rules affect SORT processing as follows: The first data byte of a fixed-length record has relative position 1.
SORT control statement
Examples of Notation for Binary Fields. Signed numeric with optional leading floating sign. The maximum length of the collected control fields for which Blockset can be used is bytes.
