True, but only under ProDOS-8 1.9 and earlier.  With ProDOS-8 2.0 and
later, the VCB entry can be re-used for "idle" disks (i.e. those which
have no open files).  Program selectors can cycle around all 14
volumes and ONLINE reports them all.

I have had at least 13 volumes online at once (not sure if I've done
14) under P8 2.0.1 and 2.0.3.
