4.16 Mlabel
===========
The `mlabel' command adds a volume label to a disk. Its syntax is:
`mlabel' [`-vcsn'] [`-N' SERIAL] DRIVE:[NEW_LABEL]
`Mlabel' displays the current volume label, if present. If NEW_LABEL
is not given, and if neither the `c' nor the `s' options are set, it
prompts the user for a new volume label. To delete an existing volume
label, press return at the prompt.
The label is limited to 11 single-byte characters, e.g.
`Name1234567'.
Reasonable care is taken to create a valid MS-DOS volume label. If
an invalid label is specified, `mlabel' changes the label (and displays
the new label if the verbose mode is set). `Mlabel' returns 0 on
success or 1 on failure.
Mlabel supports the following options:
`c'
Clears an existing label, without prompting the user
`s'
Shows the existing label, without prompting the user.
`n'
Assigns a new (random) serial number to the disk
`N SERIAL'
Sets the supplied serial number. The serial number should be
supplied as an 8 digit hexadecimal number, without spaces
