7)
Arg ERROR (Argument error): Indicates the argument of a command or specification in a program
exceeds the input range (e.g. Sci 10, Goto 11)
Further operation will become impossible when an error message is displayed.
Press

or
to cancel the error.
AC
Press
cancels the error and new key input becomes possible.
AC
With this operation, the RUN mode is maintained.
Pressing
or
cancels the error and changes the system mode to the WRT mode. The cursor is
positioned at the location where the error was generated to allow modification of the program to eliminate the
error.
4.3.3 Checkpoints for each type of error
The following are checkpoints for each type of error:
1)
Syn error: Verify again that there are no errors in the program.
2)
Ma ERROR: For calculations that require use of the memories. Check to see that the numeric values
in the memories do not exceed the range of the arguments. This type of error often occurs with
division by 0 or the calculation of negative square roots.
3)
Go ERROR: Check to see that there is a corresponding Lbl n when Goto n is used. Also chick to see
that the program in P n has been correctly input when Prog n is used.
4)
Ne ERROR: Check to ensure that the Prog command is not used in the branched program area to
return execution to the original program area.
5)
Stk ERROR: Check to see that the formula is not too long thus causing a stack overflow. If this is the
case, the formula should be divided into two or more parts.
6)
Mem ERROR: Check to see that memories were properly expanded using "
(Defm). When using array-type memories, check to see that the subscripts are correct.
7)
Arg ERROR: Check whether values specified by
within the range of 0~9. Also check whether values specified by Goto, Lbl, or Prog commands are
within 0—9. Also ensure that memory expansion using
the remaining number of steps and that the value used for expansion is not negative.
4.4 COUNTING THE NUMBER OF STEPS
The program capacity of this unit consists of a total of 400 steps.
The number of steps indicates the amount of storage space available for program., and it will decrease as programs
are input. The number of remaining steps will also be decreased when steps are converted to memories. There are two
methods to determine the current number of remaining steps:
.
1) when
are pressed in the RUN mode, the number of remaining steps will be displayed

together with the number of memories.
Example:

Basically, one function requires a single step, but there are some commands where one function requires two steps.
One function / one step: sin,cos,tan,log,(,)1,2,3 etc.
G
One function / two steps: Lbl 1 ,Prog 8 etc.

Each step can be verified by the movement of the cursor
