The OPEN.MEDIA and CREATE.MEDIA calls use the NAME argument to pass a filing system qualifier. The actual definition of this argument is BFS-specific, and can vary from BFS to BFS. Typically, the filing system qualifier is used to pass information about DOS file locations to the BFS. This corresponds to the path name passed as the physical volume name in commands such as CREATE_TABLE.

Non-Volume Media Calls
Three media calls are available even if the MFS is installed only on the file, and not on the volume:
As with other calls, these can be disabled by setting STATUS to false and returning.
