Using the DL/I test program, DFSDDLT0

You can, in some cases, use the DL/I test program (DFSDDLT0) to test DL/I call sequences or insert segments.

For example, if you need a test database with relatively few database records, you can use DFSDDLT0 to test DL/I call sequences. If you have no machine-readable database to begin with, you can define a PCB, then use DFSDDLT0 to insert segments. This step eliminates the need for a load program to generate your test database.

The DL/I Test Program cannot be used by CICS®, but can be used for stand-alone batch programs. If used for stand-alone batch programs, it is useful to interpret the database performance as it might be implemented for online or shared database programs.
