TI-83 Plus General Information
Possible Causes and Suggested Remedies
Memory is insufficient to perform the instruction or
function. You must delete items from memory (Chapter 18)
before executing the instruction or function.
Recursive problems return this error; for example,
graphing the equation Y
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.
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.
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.
