Some nuts & bolts questions.  Does anyone know how to:
(1) Change the name of a diskette volume (the name you give when FORMATting,
which gets wiped out when you BACKUP to it).  This name is stored on Track 0
and probably takes some very low-level CCDISK calls to get to.
(2) Exit the editor without updating (writing) the original file, as
 when you
screw up.  The Q command does an update automatically.  Blieve it or not,
none of the abort characters (break, ^C,^D, ^E, clear-break) will kill
the Editor; it just keeps on coming back.  So far, only the RESET button
behind the Coco will save your file.
Is the only hope to copy the file before editing?  Oversights like this
do not enhance OS-9's reputation for user-friendliness.
(3) Increase the step rate of /D1 but not of /D0.  Seems that the step rate
is in CCDISK and applies to all drives, whereas the number of tracks is
in the device descriptor tables and can be individually adjusted.  mike k
