 Hazard
    Assumes that you have checked to make sure the optionally
    specified disk drive is valid.  If the optional drive letter
    is included, the code should check ISDRIVE() first.
    Specifying an invalid drive, such as "B" on a single-floppy
    system, can cause serious errors, including
    computer lock-up and data destruction.
