LABEL MEMORY Memory Full MODE OVERFLOW RESERVED SIGN CHNG SINGULAR MAT The label in the Goto instruction is not defined with a Lbl instruction in the program. There is insufficient memory in which to perform the desired command. You must delete item(s) from memory (Chapter 15) before executing this command. Recursive problems, such as A=A+2:A, display this error. Interrupting an If/Then, For, While, or Repeat loop with a Goto that branches out of the loop can also cause this error, because the End statement that terminates the loop is never reached. Unable to transmit item because there is insufficient available memory in the receiving unit. You may skip the item or exit Receive mode. During a memory backup, the receiving unit does not have enough memory to receive all items in memory in the sending unit. A message indicates the number of bytes the sending unit must delete to do the memory backup. Delete items and try again. You are attempting to store to a WINDOW variable in another graphing MODE or to perform an instruction while in the wrong MODE, such as DrawInv in a graphing MODE other than Func. You are attempting to enter, or have calculated, a number that is beyond the range of the calculator. This error does not occur during graphing. The TI.82 allows for undefined values on a graph. You are attempting to use a system variable inappropriately. See Appendix A. The solve( function did not detect a sign change. Examine a graph of the function. If the equation has a solution, change the bounds and/or the initial guess. ¦ A singular matrix (determinate = 0) is not valid as the argument for -1. ¦ You are attempting a polynomial regression with lists that are not appropriate This error does not occur during graphing. The TI.82 allows for undefined values on a graph. Reference Information B-9
