(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
rein-
serting the disk first.
Then try using a dif-
ferent 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.
This error
could also be caused by
input/output
problems with
another device, such as the tape
recorder.
String too
Long,
characters.
NO
A
string may only be 255
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.
NEXT without FOR.
NEXT is being used without
a
matching FOR
statement. This error also occurs
when
you
have the
NEXT lines reversed in a
nested loop.
File Not
Open. You cannot input
or
output data to
a
file until you have OPENed
it.
OB Out
of Buffer space. Use FILES to
reserve more
space.
OD Out
of Data. A READ was
executed with insuffi-
cient
DATA for it
to
READ. A DATA statement
may
have been left out of the
program.
OM Out of Memory.
All available memory has been
used
or reserved.
OS Out
of String
Space.
There is not enough space
in
memory
to do
your string operations. Use
CLEAR
at
the beginning of your program to
reserve more
string space.
OV
Overflow. The number is too large
for the Com-
puter
to
handle.
RG RETURN without
GOSUB. A RETURN line is
in
your program with no
matching GOSUB.
SE
Set
to non-fielded
string. The field in which you
are attempting to
LSET or RSET data in has
not
yet been
FIELDed. Check the FIELD line.
SN Syntax error. This
could result from a
misspelled
command,
incorrect punctuation, open
parenthe-
sis, or
an illegal character. Type
the program line
or
command over.
ST String formula too
complex. A string
operation
was too
complex to handle.
Break
up
the operation
into shorter steps.
TM Type
Mismatch. This occurs
when
you
try to
assign numeric data to a
string variable (A$
=
3)
or string data to a
numeric variable
(A
=
"DATA"). This could also
occur if you do
not
enclose
a
filename
in
quotes.
UL Undefined Line.
You have
a
GOTO,
GOSUB, or
other
branching line in the
program asking the
Computer
to go
to a
nonexisting line number.
VF Verification.
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
instruc-
tions on what to do.
WP Write Protected.
You are trying to store
informa-
tion on a disk
which is Write Protected.
Either
take the
label off the write protect
notch or use a
different disk. If your
disk is not Write Protected,
then there is an input/output
problem. See 10
for
instructions on what to do about
this.
