It
is better to keep to the habit of mounting and removing the tape through
the System Display. Before carrying out a directory operation on the Microcas-
sette drive, use the System Display to check if the tape is mounted.
If
it is not
mounted, mount it through the System Display.
WARNING:
NEVER try to obtain the directory of a Microcassette tape when another
tape is already mounted. The directory of the second tape must be loaded
into memory before the directory can be printed. This can only be done
by removing the first tape and then mounting the second tape.
h) Pausing a DIRectory
Either the
I
PAuSElkey or
I
CTRL
I-[§]
can be used to pause a DIRectory as it
is displayed.
If
a directory has scrolled off the screen in screen modes 0,1 or
2, it can be seen by using the shift cursor keys (
[!]
and
m ).
i)
Printing a DIRectory
To obtain a hardcopy of a DIRectory, use
I
CTRL
I -
~
before issuing the DIR
command or use the screen dump facility (
I
CTRL
I
and the
I
PF5
I
key).
j) Stopping the DIR
If
any key is pressed during execution of this command it is terminated and
the CP/M command line reappears.

ERA
(Erasing files)
Files can be erased at any time using the ERA command. The command is used
in a similar way to the DIR command and the rules about spaces apply equally.
It
is possible to set files to be Read/Only files. Files which have been set to
Read/Only cannot be erased.
If
you really do want to erase them you can use
the STAT program to set them to Read/Write. In fact ERA does not really
erase the file from the disk - it simply removes the directory entry for it.
Files on the ROM drives cannot be erased.
If
an attempt is made to erase a
file on a drive which is set to Read/Only, one of the following error messages
will be displayed:
BDOS ERROR ON dr:FILE R/O
BDOS ERROR ON dr:R/O
will occur. The particular drive name "dr:" will be printed as the drive name
accessed.
If
this does occur you should press
I
CTRL
I -
(g ,
I
STOP lor
I
RETURN
I .
a) Erase a specific file on any drive
To do this you simply specify the full filename and extension of the file you
wish to erase:
D > ERA TESTING. COM
D>
C > ERA A:WASTE.FIL
C>
If
the file is not present the "NO FILE" message will be printed.
C> ERA DUDFILE.COM
NO FILE
C>
