DFSORT JCL (STEP SORT4)

The SORT4 program sorts the DAR4ERRS data set that is created by FABADA3. The sorted data set is used by FABADA4.

Space requirements for the various work data sets created by SORT4 are summarized in the following table. Most output data sets do not require DCB information to be specified in your JCL.

Table 1. DEDB Pointer Checker SORT4 data set sizes
DDNAME	Space required
SORTOUT	< 1 cylinder

EXEC statement

This statement must be in the following form:

//     EXEC PGM=SORT

DD statements

To run DFSORT, you have to supply the appropriate DD statements. The following table summarizes the DD statements needed to run DFSORT. All statements in this table are required.

Table 2. DFSORT DD statements (Step SORT4)
DDNAME	Use	Format	Required or optional
SORTIN	Input		Required
SYSIN	Input		Required
SORTOUT	Output		Required
SYSOUT	Output	SYSOUT	Required
SORTWK01	Work data set		Required
SORTWK02	Work data set		Required
SORTWK03	Work data set		Required

SORTIN DD: This input data set is the DAR4ERRS file from FABADA3.
SYSIN DD: This input data set contains DFSORT control statements. It is the SORT4CTL file from FABADA3.
SORTOUT DD: This output data set contains the sorted records. It is used by FABADA4. Required space is the same size as the SORTIN data set. Do not specify DISP=MOD for this DD statement.
SYSOUT DD: This output data set contains the message produced by DFSORT.
SORTWKnn DD: These are intermediate storage data sets used by DFSORT. See DFSORT Application Programming Guide for more information about coding SORTWKnn DD statements.
Allocating twice the space used by the SORTIN data set is usually adequate for each work data set.
