Error Number Description 163 Attribute (8-digit number) of object (8-digit number) not found 165 Batteries too low for sending or receiving Install new batteries before sending or receiving. 170 Bound For the interactive graph math functions like 2:Zero, the lower bound must be less than the upper bound to define the search interval. 180 Break The ´ key was pressed during a long calculation or during program execution. 185 Checksum error 190 Circular definition This message is displayed to avoid running out of memory during infinite replacement of variable values during simplification. For example, a+1! a, where a is an undefined variable, will cause this error. 200 Constraint expression invalid For example, solve(3x^2- 4=0, x) | x5 would produce this error message because the constraint is separated by "or" and not "and." 205 Data is too big to save to a variable. Please use F6 Util to reduce the size. The size of the data in the editor exceeds the maximum size that can be saved in a variable. The F6 Util menu provides operations that can be used to reduce the size of the data. 210 Data type An argument is of the wrong data type. 220 Dependent limit A limit of integration is dependent on the integration variable. For example, ä‰(x^2,x,1,x) is not allowed. 225 Diff Eq setup 230 Dimension A list or matrix index is not valid. For example, if the list {1,2,3,4} is stored in L1, then L1[5] is a dimension error because L1 only contains four elements. 240 Dimension mismatch Two or more arguments must be of the same dimension. For example, [1,2]+[1,2,3] is a dimension mismatch because the matrices contain a different number of elements. 250 Divide by zero 260 Domain error An argument must be in a specified domain. For example, ans(100) is not valid because the argument for ans() must be in the range 1- 99. 270 Duplicate variable name Appendix B: Technical Reference 916
