Yes! I forgot all about that one. Thank you, Laddie, for mentioning it. That would also be a viable method for Bertram:

Note: The above TMOUNT assembler source code was written for the DOS/VSE operating system, but the program is so short and simple that I would like to believe any competent assembler programmer should have no problem understanding it, given that the most important part is how the CCWs are used. How I/O to a device is done on other operating systems is left to the user.

Caution: writing a channel program you need to know about
how I/O works and can be very difficult to debug.
I guess it all depends on how complicated the I/O is. In the TMOUNT case, the I/O is so dirt simple that I'm doubting there would be any significant problems.
