Ideal batch has a limit of 16 sequential Dataviews concurrently opened per each step.
Is there any command or method to force the close of a sequential dataset before the job step completes?
There is no RELEASE command for sequential dataviews, so that means the limit of 16 sequential files per IDEAL batch STEP cannot be exceeded.
The sequential dataview file is closed is at the end of the STEP.
The only way to exceed the limit would be with a RUN in a second STEP for the additional sequential dataviews.
