Error
Number
Description
160 Argument must be an expression
For example, zeros(2x+3=0,x) is invalid because the first argument is an equation.
161 ASAP or Exec string too long
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
ì
4=0, x) | x<0 or x>5 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,
‰
(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.
