Workfile Hierarchical Sort (Step 5)

The JCL to hierarchically sort the workfile from Step 4 is shown below:

Workfile Hierarchical Sort (Step 5) (z/OS)

//SORT  EXEC  SORT
//SORTIN DD DSN=step4.workfile,DISP=OLD,UNIT=TAPE
//SORTOUT DD DSN=step5.workfile,DISP=OLD,UNIT=TAPE
//SORTWK01 DD UNIT=DISK,SPACE=(CYL,(1),,CONTIG)
//SORTWKO2 DD UNIT=DISK,SPACE=(CYL,(1),,CONTIG)
//SORTWK03 DD UNIT=DISK,SPACE=(CYL,(1),,CONTIG)
//SYSIN  DD *
SORT  FIELDS=(17,8,BI,A)
/*
//

Note: This step requires that you use your own sort/merge facility.
