We had DYNAM/T years ago. As I recall, there was a parameter you could set
that would close a tape after it had been open for a given amount of time. I
think we had it set to 8 hours.

Another possibility...We're now using EPIC and I had a similar problem - EPIC
wouldn't catalog a new tape until it was closed. For a while I had operators
mounting what they (and EPIC) thought were scratch tapes for other jobs,
overwriting ADSM data. So I modified DSMMOUNT to close the dataset
immediately after the tape mount. I don't know if this will work with DYNAM
but it fixed my problem.
