As an alternative to running in batch mode, you may invoke the following routine to run the VIT analysis tool interactively. If you choose this method for processing, your terminal will be unavailable until processing is completed.

18	Invokes the VIT analysis tool, assuming that it has been installed in the SYS1.MIGLIB load library.
20	Frees the data sets allocated to the DD name statements to allow the exec to run again with different data set names.

Note:

The DD parameters are required. The DSN parameters are optional and can be varied.
Return codes are not checked in this example.
Your user terminal will not be available while the tool is active.
