A few of them are listed below with their functionality:. All fields must be completely contained within the first bytes of the record. Two-digit packed-decimal year data.
The cultural environment is established by selecting the active collation version. Packed decimal xxyy and xxxxyy full date format with special indicators.
SORT control statement
Specify E if you include an E61 user exit to modify control fields before the program sorts them. Frequently used sort tricks using these utilities are explained in the next chapter. When you determine the total, count a xfsort field as occupying an entire byte if it occupies any part of it. A binary field beginning on the third bit of the third byte of a record is represented as 3.
Signed numeric with trailing overpunch sign. Remember that the first high-order bit of a byte is bit 0 not bit 1 ; the remaining bits are numbered 1 through 7. 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. All floating-point data must be normalized before the program can collate it properly.
Two-digit character or zoned-decimal year data. These utility programs need to be used with appropriate DD statements in a JCL in order to achieve the specified functionality.
Packed decimal yyx and yyxxx full date format with special indicators.
JCL – Utility Programs
Two-digit decimal year data. If this maximum is exceeded, Blockset cannot be used. The first 4 bytes contain the record descriptor word. A control field 2 bits long would be represented as 0. Rfsort provides sorting for single-or multi-byte character data based on defined collating version rules that retain the cultural and local characteristics of a language.
Signed numeric with leading overpunch sign. The active locale’s collating rules affect SORT processing as follows: First, specify the byte location relative to the beginning of the record and follow it with a period.
Character with alternate collating sequence. The maximum length of the collected control fields for which Blockset can be used is bytes.
The options available on the SORT statement can be specified in other sources as well. For example, a binary field that begins on byte 2. Character or zoned x You can use an E15 or E61 user exit to do this during processing. Unicode Transformation Format, uttility 16 bit encoding form. Packed decimal yyxx and yyxxxx full date format with special indicators.
Unsigned free form numeric. For example, the following are all equivalent: A SORT statement can also be used to specify a copy application. Unicode Transformation Format, a 8 bit encoding form.
