LABEL
The label in the
Goto
instruction is not defined with a
Lbl
instruction in the program.
MEMORY
There is insufficient memory in which to perform the desired
command. You must delete item(s) from memory (Chapter
15) before executing this command.
Recursive problems, such as
A=A+2:A
, display this error.
Interrupting an
If
/
Then
,
For
,
While
, or
Repeat
loop with a
Goto
that branches out of the loop can also cause this error,
because the
End
statement that terminates the loop is never
reached.
Memory Full
Unable to transmit item because there is insufficient
available memory in the receiving unit. You may skip the item
or exit
Receive
mode.
During a memory backup, the receiving unit does not have
enough memory to receive all items in memory in the sending
unit. A message indicates the number of bytes the sending
unit must delete to do the memory backup. Delete items and
try again.
MODE
You are attempting to store to a
WINDOW
variable in another
graphing
MODE
or to perform an instruction while in the
wrong
MODE
, such as
DrawInv
in a graphing
MODE
other
than
Func
.
OVERFLOW
You are attempting to enter, or have calculated, a number
that is beyond the range of the calculator. This error does not
occur during graphing. The TI
.
82 allows for undefined values
on a graph.
RESERVED
You are attempting to use a system variable inappropriately.
See Appendix A.
SIGN CHNG
The
solve(
function did not detect a sign change. Examine a
graph of the function. If the equation has a solution, change
the bounds and/or the initial guess.
SINGULAR MAT
¦
A singular matrix (determinate = 0) is not valid as the
argument for
-1
.
¦
You are attempting a polynomial regression with lists that
are not appropriate
This error does not occur during graphing. The TI
.
82 allows
for undefined values on a graph.
