Sort Programs Interface

This chapter includes the following topics:

• Overview

• DFSORT Implementation

• SyncSort Implementation

Overview

Control-M/Tape provides an interface with DFSORT and SyncSort. Before the sort program reads a data set that resides on a tape, it issues queries for the data set attributes, such as record length, block size, record format, and block count. Using the responses to these queries, the sort program improves its performance.

DFSORT Implementation

You can implement DFSORT by copying the CTTTPEX module from the IOA.LOAD library into the DFSORT load library, or to the LNKLST.

SyncSort Implementation

You can implement SyncSort by copying the CTTSI module from the IOA.LOAD library into the SyncSort load library, or to the LNKLST.
