MOUNT OFF: unmount the virtual disk controller from BASIC #123

Open dansanderson opened 4 months ago

dansanderson commented 4 months ago

There is currently no way to unmount the virtual disk controller from BASIC. You can do this from the Freezer by selecting "no disk" from the disk image browser. For completeness, it would be nice to be able to do this from BASIC also.

MOUNT OFF and MOUNT OFF,U8 would unmount the first virtual drive. MOUNT OFF,U9 would unmount the second virtual drive.

This syntax is proposed to avoid creating a keyword. ("OFF" is an existing keyword.)

I have a comprehension problem here: Is there a practical use case for an UNMOUNT or MOUNT OFF of a D81 image? If I want to use a different image, I mount it and the previous image is replaced. For what practical reason should you unmount an image if you don't want to mount another one?

Honestly I don't know, I don't think there's a practical advantage. More than one person has requested this feature over the years so I created an item for it. I think it just feels conceptually incomplete to some people that there is a state that the virtual drive can be in that can't be reached by the user. It's a capability of the Freezer, so if it's easy to do (as in, only a few bytes of ROM code) we can add it to the MOUNT command.

... I would personally rule this as very low priority and it may not be implemented. This issue exists to gather feedback. :)

I have nothing against such a command being implemented. ;-)

I was just wondering why it would ever be needed. :-)
