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. .

Signed numeric with leading separate sign.

The total number of bytes occupied dfsott all control fields must not exceed or, when the EQUALS option is in operation, bytes.

Two-digit decimal year data. A binary field beginning on the third bit of the third byte of a record is represented as 3. Signed numeric with leading overpunch 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 the record.

Using the ICETOOL utility

Usually used to manage VSAM datasets. All control fields, except binary, must begin on a byte boundary. PD nines, upper century dates for example, 20yyutlity century dates for example, 19yyPD zeros. Packed decimal xxyy and xxxxyy full date format with special indicators. See Data format descriptions for detailed format descriptions. Unicode Transformation Format, a 16 bit encoding form. Frequently used sort tricks using these utilities are explained in the next chapter.


DFSORT produces sorted records for output according to the collating version rules defined in the active collation version. Thus the Y2 formats will collate real dates and special indicators as follows: This provides sorting for single-or multi-byte character data utilty on defined collating version rules that retain the cultural and local characteristics of a tuility. A few of them are listed below with their functionality:.

First, specify the byte location relative to the beginning of the record and follow it with a period. 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. BI ones, upper century years for example, 20yy dfsorr, lower century years for example, 19yyblanks, BI zeros. You can use an E15 or E61 user exit to do this during processing.

Lower century years for example, 19yyupper century years for example, 20yy. None; must be specified.

It gives best utilization of system resources and efficient operation in bit and bit address spaces. Specify E if you include an E61 user exit to modify control fields before the program sorts them. It can compare two or more files on specified field s and create one or more output files like file with matching records, file with non-matching records, etc.


Two-digit binary year data. The first data byte of a fixed-length record has relative position 1. All floating-point data must be normalized before the program can collate it properly. If this maximum is exceeded, Blockset cannot be used.

Two-digit packed-decimal year data. Packed decimal xyy and xxxyy full date format with special indicators. Usually, this is not recommended in view of performance for large files.

Character with alternate collating sequence. The number of bits specified must not exceed 7.

DFSORT example

The first 4 bytes contain the record descriptor word. Input and output datasets can be defined using user defined DD names.

Requires four facts about each control field in the input records: Two-digit character or zoned-decimal year data with special indicators. Then, specify the bit location relative to the beginning of that byte. Packed decimal yyxx and yyxxxx full date format with special utiljty. The active collation version rules affects SORT processing as follows: The active locale’s collating rules affect SORT processing as follows:
