reference Y, XMIN, @X, or TBLMIN.

INVALID DIM ¦The dimension of the argument is not appropriate for the

99; for example, L1(100) will cause an error.

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

NEST LEVEL This error occurs when any nested combination of function

evaluation, NDERIV( or SEQ( exceeds 5 levels.

OVERFLOW You are attempting to enter, or you have calculated, a

does not occur during graphing. The TI-80 allows for

undefined values on a graph.
