z/OS : Débuter avec DFSORT
Signals the initiation of a job. Signals the initiation of a step. Dfsorf OS which program is to be executed. Defines the input dataset that needs to be sorted.

For variable length files the file with largest record length must be first. Used for merge request ih files. The ‘nn’ suffix can be any number in the range 00 thru 99; they may be skipped or used out of order. The ‘nn’ suffix can be any number in the range 00 thru Defines the output dataset.
The ‘nn’ suffix can be any number in the range 00 through They may be skipped or used out of order.
Sorting means Rearranging data in either ascending or descending order. Determines whether or not the sort will preserve the order of records with identical sort fields.
Merge two or more datasets to form a single dataset. Remember that dsort is different from concatenating.
Concatenating means data is just appended back to back. With merging sort order is maintained. The sort order ‘A’ indicates the order in which the data is already sorted in the input files. Nn stands for 01 to Used to establish selection criteria for records to be included in the output dataset.
We can compare the contents of its fields to a constant or another field in the record. The AND and OR relational operators are used to link together as many repetitions of the ‘expression’ field as desired. Used to set up selection criteria for records to be dfsoft from the output dataset. We can omit a record by comparing contents of its fields to a constant or another field in the record.
The SUM control statement deletes records with equal control fields and optionally summarizes specified numeric fields on those records. If numeric fields are to be summarized, the data in the summary fields is added, the sum is placed in one of the records, and the other record is deleted. We could use XSUM if we want to save off the remaining records.
This is where the discards will go. Formatting will be done before sortingmerging or copying of the records is done.

In short operation will be performed on the input file. In this statement, 3 data fields are specified as follows:. It will be in position 1 of the dvsort record. The field will be converted to PD. It will be in position 21 of the output record.
It will be in position 29 of the output record.
IN the above example we used absolute positioning using “: We can also just specify the position in input file and it will create fields back to back. Formatting will be done after sorting or merging is done.
In short Operation will be performed on the output file. This task uses these parameters: The number nn will be used as fileid. This will Create a output file without the 1st field characters. This will put 20 blank fields before 1st field and 16 blank spaces before 2nd field. Posted by cobolbasics at Unknown 25 February at Sunny shailendra 19 July at Defines the output jc for messages.
