A GARBLED UP
DISK
WHEN
THINGS
GO
WRONG
Your
Computer
realizes
nobody's
perfect.
When
you
make a
mistake,
it'll try to
notify you
imme-
diately
and
tell you
what
kind of
"error" you
made.
You've
probably
already
been notified
that you
made a
"SN
ERROR."
If you
haven't, type
DIIR
[ENTER)
deliberately
mispelling
DIR.
SN
means
"Syntax"
error.
It's the
Computer's way
of
telling you
that
"DIIR"
doesn't make
sense to it.
The
word is
not in
its vocabulary.
An SN error
usually
means you made a
typographical
error.
Here
are some
other
error messages
you're
likely
to get
with your
disk system:
AE —You
are
trying
to
RENAME a file
(discussed
in
the
next chapter) to a
filename which
Already
Exists.
DF —The
Disk you
are trying to
store
your file on
is
Full. Use
another disk.
DN —You
are
using
a
Drive
Number
higher than
3. You
will also get
this
error if you do
not
specify
a
drive
number when
using DSKINI
or
BACKUP. If you
have
only one
drive
specify
drive
with these two
commands
(DSKINIO or
BACKUP
0)
FN
—
You
used
an
unacceptable format to
name
your
file. The
last Chapter
explains
which
File
Names
are acceptable to
the
Computer.
FS —
There is
something
wrong with your
disk
file. See 10 for
instructions on
what
to
do.
/0
—Technically,
this
means you have
asked the
Computer to
divide a
number by
0,
which is
impossible. However, you
might also get
this error
when you don't
enclose
a
filename
in
quotation marks.
10
—The
Computer is
having
trouble
Inputting
or
Outputting
information to
the
disk.
(1)
Make sure
there is a
disk
inserted
properly in
the
indicated
drive and
the
drive door
is closed.
(2)
If you
still get
this error,
there
might
be
something
wrong
with
your disk.
Try
reinserting
the
disk first.
Then try
using
a
different
one or
reformatting
it.
(Remember
that
reformatting a
disk erases
its contents.)
(3)
If you
still get
this
error, you
probably
have a
problem
with the
Computer
System
itself.
Call the
Radio Shack
Repair Center.
NE —The Computer
can't
find the
disk file you
want.
Check the
disk's
directory to see
if the
file is
there. If you
have
more than
one disk
drive, you
might
not have
included
the
appropriate
drive
number in the
filename.
If
you
are
using COPY,
KILL,
or
RENAME
(discussed
in the
next chapter),
you
might
have left
off the
extension.
TM —
Technically
this is
caused by a
program
which
mixes
"strings"
with
"numbers."
However,
you
might get
this error
if you
don't
enclose a
filename
in quotation
marks.
UF —You
will only get
the error
when you
have
the
VERIFY
command ON
and are
writing
to a
disk. The Computer
is
informing you
that
there is
a
flaw
in what
it wrote. See
10
for
instructions on
what to do.
W P
—
You are
trying to
store
information on a
disk
which is Write
Protected.
Either
take the
label off
the write protect
notch
or use a
dif-
ferent
disk. If
your disk is not
Write
Pro-
tected, then
there is an
input/output
prob-
lem.
See
10 for instructions
on
what
to
do
about
this.
All other errors you
might get
are
errors in
the
program you
are using.
If you did
not write
the
program
and get one
of these
errors, you need to
contact the
people who
wrote it. If you
did write
it,
check Appendix G,
where
you'll find an
explana-
tion of all the
error messages.
