SORT Operator
SORT Operator (for Experienced)
Summary
For basic information, go through the SORT Operator (for Beginners)
- SORT operator sorts a dataset into one or more output datasets.
- SORT operator allows up to 10 input datasets.
- The DFSORT control statements in xxxxCNTL are used if USING(xxxx) is specified.
- DFSORT control statements are used to copy a subset of the input records, reformat records, etc.
Syntax -
Required Operands
FROM -
- FROM parameter specifies ddname of the input file.
- indd DD statement is mandatory if FROM operand specified.
JKFROM -
- JKFORM is used for a JOIN KEYS application.
- JKFROM is mandatory for USING(xxxx) operand.
- In xxxxCNTL, a JOINKEYS statement should provide F1=ddname1 for the F1 file, F2=ddname2 for the F2 file, JOIN and REFORMAT statements according to the requirement.
USING -
- USING operand specifies the first 4-characters of the ddname (xxxxCNTL) for the DFSORT control statement file.
- XXXX name is the user-defined name.
- xxxxCNTL DD statement is mandatory if USING(xxxx) is specified.
- Either TO, USING, or both operands can code at the same time.
Optional Operands
TO -
- TO operand specifies 1 to 10 ddnames of output files.
- outdd DD statement is mandatory if TO operand specified
- Either TO, USING, or both operands can code at the same time.
VSAMTYPE -
- VSAMTYPE operand specifies the record format for a VSAM input file (F or V).
Example -
Scenario - Sort the employee records based on employee name (15 character length from 6th position).

******************************** BOTTOM OF DATA ******************************************Explaining Solution -
- INDD - Specifies the ddname for input file.
- OUTDD - Specifies the ddname for output file.
- TOOLIN DD * - Specifies the ICETOOL statements for DFSORT.
- TOOLMSG - Specifies where to write the ICETOOL processing messages.
- DFSMSG - Specifies where to write the DFSORT processing messages.
- CTL1CNTL DD * - Specifies the DFSORT statements for processing.
- SORT FROM(INDD) TO(OUTDD) USING(CTL1) - Sorts the indd records and copies to OUTDD based on the selection criteria in CTL1.
- SORT FIELDS=(50,2,CH,A) - Sorts the records in ascending order based on the data of length 15 from 6th position.
