SORT Operator
Sorts the records (SORT Operator)
SORT operator sorts the records in the input file and copies the records into the output files. It allows up to 10 input files.
Syntax -
Required Operands
- FROM - specifies ddname of the input file. It is mandatory when FROM operand is coded.
- JKFROM - used to JOIN KEYS for matching records. It is mandatory when USING(xxxx) is coded. 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 - specifies the first 4-characters of the ddname (xxxxCNTL) for the DFSORT control statement. XXXX name is the user-defined name. Either TO, USING, or both operands can code at the same time.
Optional Operands
- TO - specifies 1 to 10 ddnames of output files. TO and USING operands can code at the same time.
- VSAMTYPE - specifies the record format for a VSAM input file. It should be either F (fixed-length) or V (variable-length) record processing.
Example -
Scenario - Sort the employee records based on employee name (15 character length from 6th position).
