Error Type Possible Causes and Suggested Remedies
ILLEGAL NEST
You attempted to use an invalid function in an
argument to a function, such as
seq(
within
expression for
seq(
.
Can occur when combinations of nesting of function
evaluation exceeds five levels.
INCREMENT
The increment in
seq(
is 0 or has the wrong sign. This
error is not returned during graphing. The TIN73
allows for undefined values on a graph.
The increment in a
For(
loop is 0.
INVALID
You attempted to reference a variable or use a
function where it is not valid. For example,
Yn
cannot reference
Y
,
Xmin
, @X, or
TblStart
.
Defining and graphing a
Yn
equation using the
variable
Ans
.
You attempted to use
Select(
without having selected
(turned on) at least one xyLine or Scatter plot.
INVALID DIM
You specified dimensions for an argument that are
not appropriate for the operation.
You specified a list dimension as something other
than an integer between 1 and 999.
ITERATIONS
The Equation Solver has exceeded the maximum
number of permitted iterations.
Examine a graph of the function. If the equation has
a solution, change the bounds, the initial guess, or
both.
LABEL
The label in the
Goto
instruction is not defined with a
Lbl
instruction in the program.
