>Are you happy with the $QIO system service?

        Yes, Jamie, I sure am.  I'm even happy with the driver
        interface.  When you've got someone as ornery as me
        happy with both sides of an I/O subsystem, that's a good
        place to quit and go have a beer.

        To a large degree yes.  I would however provide an RTL equivalent
        (LIB$IO?) which had the following arguments:
            lib$io(chan,func,itmlst)

        While that wouldn't work for everything, it would do synchronous
        I/O with internal $SYNCH.
