CHANGE in OUTREC statement can be used to look up and change the content in the file while sorting. Build parameter is used to reformat records. Build give complete control over output file format. BUILD parameter can be used on INREC and OUTREC statements in SORT card. BUILD parameter is an alias of the FIELDS […]

You can use the INCLUDE OMIT Substring Comparison statement in conjunction with other options to select/omit the number of records to be processed, which can reduce processor and data transfer time. There are two types of INCLUDE OMIT Substring Comparison tests: Find a constant within a field value: For example, search the value in a

You can convert an FB data set to a VB data set with OUTFIL’s FTOV parameter. Each VB output record has a 4-byte RDW followed by the corresponding data from the FB input record, and the length in the RDW is the length of the FB record plus 4. The following JCL and DFSORT control

The VTOF utility is a tool designed to perform the conversion from VB to FB format. It is commonly used in mainframe environments, where data files are often stored in fixed-length record formats for efficiency and ease of processing. You can use OUTFIL – VTOF and BUILD or OUTREC parameters. All these PARSE, BUILD, or

VLSCMP and VLSHRT are the utilities used with VB files. In VB records always add 4 to the starting position. This is to account for the 4-byte RDW. For example, the following INCLUDE statement compares a PD field in the third through fifth data bytes of a VB record to a PD field in the

DYNALLOC PARM: This option requests the dynamic allocation of SORTWK data sets. DYNALLOC=OFF can be specified to override a DYNALLOC=ON installation default. If DYNALLOC has been specified on the SORT control statement as well as in the PARM field, the PARM specification will take precedence. ZDPRINT PARM: This option applies to the SUM, DUPKEYS SUM, and

SEQNUM creates & inserts sequence numbers in the output record. The sequence numbers are assigned in the order in which the records are received for INREC processing. The length of the field can be from 1 to 16 bytes. It is in BI, PD, or ZD formats. A starting value and an increment can be

ICETOOL is a batch front-end utility that uses the capabilities of DFSORT toperform the operations you request. Input and output datasets can be defined using user-defined DD names. The file operations are specified in the TOOLIN DD statement. Additional conditions can be specified in user-defined ‘CTL’ DD statements. A few of the utilities of ICETOOL

Fill Method Paired and unpaired records – This example illustrates an alternative way to create three output files; paired F1/F2 records, unpaired F1 records, and unpaired F2 records. It produces the same output as Example 5. Whereas Example 5 uses an indicator in one position to determine where the key was found, Example 6 uses

Indicator method: Paired and unpaired records – This example illustrates how you can create three output files; paired F1/F2 records, unpaired F1 records, and unpaired F2 records. In this case: F1 records which do not have a match in F2 on the specified keys (for example, key=David) will be written to the F1ONLY output file.

Unpaired records F2: This example illustrates how you can select only unpaired records from one of two files. In this case, we will select the F2 records that do not have a match in F1 on the specified keys (for example, key1=Molly and key2=2100). We will also omit certain records from each input file and

Paired records F1 – Below example illustrates how you can select only paired records from one of two files. In this case, we will select the F1 records that have a match in F2 on the specified keys (for example, key1=Development and key2=Master). The F1 records are in comma-delimited form so we will parse them

Paired records with duplicates: This example illustrates how you can join paired records from two files, both of which have duplicate records. The result will be a cartesian join. The paired records are the records in F1 and F2 with matching keys (for example, key=Cats). Paired records with duplicates Example //SEP002 EXEC PGM=SORT //SYSOUT DD

Paired records without duplicates – ASA (formerly ANSI)control characters appear in Position 5 for variable-length records (just after the Record Descriptor Word (RDW)). So coding REMOVECC on the OUTFIL statement suppresses the control characters. This example illustrates how you can join paired records from two files using multiple keys. In this case, neither file has

JOINKEYS feature joins transactions/records from two different files based on certain keys (i.e. fields with common information). The SORTJNF1 and SORTJNF2 DD statements were used to specify these files. Each JOINKEYS statement must specify the DDNAME of the file it applies to and the starting position, length, and sequence of the keys in that file. You

In SORT JCL, the STOPAFT SKIPREC are two conditions that control the processing of input records. You can use the STOPAFT SKIPREC options to reduce the number of records to be processed, which can reduce processor and data transfer time. STOPAFT and SKIPREC are optional parameters and can be used together or separately in a

You can use the INCLUDE OMIT statement in conjunction with other options to select/omit the number of records to be processed, which can reduce processor and data transfer time. The INCLUDE and OMIT statements allow you to select records by comparing fields with constants or other fields. Only one INCLUDE/OMIT control statement can be specified
