DFSORT JCL (Step SORT12)

This program sorts the MEDAR12O data set that is created by FABBME3. The sorted data set is used by FABADA5.

EXEC statement

The EXEC statement must be in the following form:

//     EXEC PGM=SORT

DD statements

To run DFSORT, you must supply the appropriate DD statements. The following table summarizes the DD statements. Actual JCL requirements are as follows:

Table 1. DFSORT DD statements (Step SORT12)
DDNAME	Use	Format	Required or optional
SORTIN	Input	LRECL=20	Required
SYSIN	Input		Required
SORTOUT	Output	LRECL=20	Required
SYSOUT	Output	SYSOUT	Required
SORTWK01	Work data set		Required
SORTWK02	Work data set		Required
SORTWK03	Work data set		Required

The following table shows space requirements for this JCL stream.

DDNAME	Space requirements
SORTOUT	# CI/area X 1.5 X 20 bytes

SORTIN DD: This input data set is the MEDAR12O file from FABBME3.
SYSIN DD: This input data set contains DFSORT control statements. It is the SORT12 file from FABBME3.
SORTOUT DD: This output data set contains the sorted records. It is used by FABADA5. 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 messages produced by DFSORT.
SORTWKnn DD: These are the intermediate storage data sets used by DFSORT. See DFSORT Application Programming Guide for more information about creating SORTWKnn DD statements.
Allocating twice the space used by the SORTIN data set is usually adequate for each work data set.
