A function or instruction is archived and therefore cannot be
executed or edited. Use the unarchive command to unarchive
the variable before using it.
A function or instruction does not have the correct number of
arguments. See Appendix A and the appropriate chapter.

¦ Your guess and several points around it are undefined.
Examine a graph of the function. If the equation has a solution,
change the bounds and/or the initial guess.

You pressed the É key to break execution of a program, to
halt a instruction, or to stop evaluation of an expression.
DRAW
You entered a value or variable that is the wrong data type.
¦ For a function (including implied multiplication) or an
instruction, you entered an argument that is an invalid data
type, such as a complex number where a real number is
required. See Appendix A and the appropriate chapter.
¦ In an editor, you entered a type that is not allowed, such as a
matrix entered as an element in the stat list editor. See the
appropriate chapter.
¦ You attempted to store to an incorrect data type, such as a
matrix, to a list.
You attempted to perform an operation that references more
than one list or matrix, but the dimensions do not match.
¦ You attempted to divide by zero. This error is not returned
during graphing. The TI-82 STATS allows for undefined
values on a graph.
¦ You attempted a linear regression with a vertical line.
