Non-BS2000 tape files

Tape files which were not created under BS2000 are treated just like non-cataloged
BS2000 files. However, due to the often widely different principles underlying the operating systems, the full degree of access protection is not always possible. For volumes and files with standard labels in accordance with DIN 66029, owner protection is assured if the VOL1 label contains the owner identifier and neither the volume nor the files is/are shareable.
