STAT drivename: =
R/O
An
entire disk can be set to read/only with this command.
It
remains effective
until either a warm or a cold start
is
made:
C>STAT
A:=R/O
The Read/Only command protects the files on a disk so
that
they cannot be
erased
or
written to.
If
you try to write
or
erase a file with a
R/O
attribute
set the error message:
A>
ERA LETTER.DOC
BDOS
ERROR
ON
A:R/O
will be displayed.
Pressing either the
I RETURN 1 key or thel STOP
Ikey
or I CTRL
1-
(g
will return
3-48
you to the prompt.
It
is
also possible
to
protect single files and unprotect them using STAT.

of
the file until it
is
reset to read/write:
C>STAT
A:DOCUMENT.TXT

$SYS
It
is
possible to give a file SYStem status using this command. This effectively
removes its name from the directory so it cannot be used by anyone who does
not
know it exists:
C>STAT
