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/receiving product code
Install new batteries before sending or receiving product software (base
code).
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.”
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.
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
