ITERATIONS
•The solve( function or 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,
or the initial guess, or both.
irr( has exceeded the maximum number of
permitted iterations.
When computing æ, the maximum number of
iterations was exceeded.
LABEL
The label in the Goto instruction is not defined with
a Lbl instruction in the program.
MEMORY
Memory is insufficient to perform the instruction or
function. You must delete items from memory
before executing the instruction or function.
Recursive problems return this error; for example,
graphing the equation Y1=Y1.
Branching out of an
If/Then, For(, While, or Repeat
loop with a
Goto also can return this error because
the End statement that terminates the loop is never
reached.
MemoryFull
You are unable to transmit an item because the
receiving unit’s available memory is insufficient.
You may skip the item or exit receive mode.
During a memory backup, the receiving unit’s
available memory is insufficient to receive all
items in the sending unit’s memory. A message
indicates the number of bytes the sending unit
must delete to do the memory backup. Delete
items and try again.
MODE
You attempted to store to a window variable in
another graphing mode or to perform an instruction
while in the wrong mode; for example, DrawInv in a
graphing mode other than
Func.
