How do you sort in ascending order in JCL?
DFSORT TUTORIAL REFERENCE STUDY MATERIAL – SORT JCL – IBM MAINFRAME. EXPLANATION 1. SORT FIELDS=(1,3,CH,A) Input file will be sorted depending up on the key specified above 1,3,CH,A – key starting position is 1 and length 3, comparing type character, sorting is don in ascending order 2.
What is equals in sort JCL?
EQUALS: specifies that the original sequence must be preserved. NOEQUALS: specifies that the original sequence need not be preserved. For sort applications, the sequence of the output records depends upon the order of: The records from the SORTIN file.
What is ZD In sum fields?
Designates numeric fields in the input record as summary fields. specifies the length in bytes of the summary fields to be added….SUM control statement.
| Summary Field Formats and LengthsFormat Code | Length | Description |
|---|---|---|
| ZD | 1 to 31 bytes | Signed zoned decimal |
How do you SORT in descending order in JCL?
SORT FILEDS statement sorts the records in descending order based on the newly added sequence number. OUTREC BUILD – As the sequence number is not required in output, this build statement copied the actual data till 35th position.
What is option in sort?
SORT command is used to sort a file, arranging the records in a particular order. By default, the sort command sorts file assuming the contents are ASCII. Using options in the sort command can also be used to sort numerically. SORT command sorts the contents of a text file, line by line.

The Sort/Merge utility is a mainframe program to sort records in a file into a specified order, merge pre-sorted files into a sorted file, or copy selected records.
What is optoption vlshrt?
OPTION VLSHRT. SORT FIELDS=(15,5,CH,A) VLSHRT tells DFSORT that you want to temporarily replace any missing control field bytes with binary zeros (the zeros are not kept for the output record), thus allowing DFSORT to validly sort or merge on the short control fields.
What is the use of (15 5 Ch a) in vlshrt?
SORT FIELDS= (15,5,CH,A) VLSHRT tells DFSORT that you want to temporarily replace any missing control field bytes with binary zeros (the zeros are not kept for the output record), thus allowing DFSORT to validly sort or merge on the short control fields.
What is the difference between novlshrt and vlscmp in DFSORT?
VLSHRT: Specifies that DFSORT continues processing if a short control field, compare field or summary field is found. NOVLSHRT: Specifies that DFSORT terminates if a short control field, compare field or summary field is found. VLSCMP: Specifies that short variable-length compare fields are padded with binary zeros.
Can I use nosolrf instead of solrf for SORTOUT LRECL?
If you want DFSORT to use the input length for the SORTOUT LRECL even when INREC or OUTREC is present, you can use NOSOLRF, but be aware that this can cause padding or truncation of the reformatted records, or termination. CAOUTREC can be used instead of SOLRF.
