This command forces the QL to forget that it had already read a
cartridge in the given microdrive mdvn\_. This could be necessary if
cartridges are exchanged between QLs, otherwise one of the QLs may not
find a file written by another QL on a cartridge. Such problems do not
exist with floppies or any other media.
