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) | 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,
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
