©M em ERROR (Memory error)
Indicates the attempt to use a memory name such as Z [5] without having
expanded memories.
©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 ES, ® , or E>) to cancel the error.
Pressing ^ cancels the error and new key input becomes possible.
With this operation, the RUN mode is maintained.
Pressing dE) or E3 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.
■Checkpoints for each type of error
The following are checkpoints for each type of error:
©Syn ERROR
Verify again that there are no errors in the program.
© M a 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.
© G o ERROR
Check to see that there is a corresponding Lbl n when Goto n is used. Also
check to see that the program inP« has been correctly input when Prog n
is used.
@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.
© S tk 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.
