Appendix
Meaning
1 Calculation formula contains an
error.
2 Formula in a program contains
an error.
1 Calculation result exceeds
calculation range.
2 Calculation is outside the input
range of a function.
3 Illogical operation (division by
zero, etc.)
4 Poor precision in differential
calculation results.
1 No corresponding Lbl n for
Goto n .
2 No program stored in program
area Prog “file name”.
3 No corresponding “Next” for
“For”, no corresponding
“LpWhile” for “Do”, or no
corresponding “WhileEnd” for
“While”.
• Nesting of subroutines exceeds
10 levels.
Countermeasure
1 Use d or e to display the
point where the error was
generated and correct it.
2 Use d or e to display the point
where the error was generated
and then correct the program.
123
Check the input numeric value
and correct it.
When using memories, check
that the numeric values stored
in memories are correct.
4 Try using a smaller value for ∆ x
( x increment/decrement).
1 Correctly input a Lbl n to corres-
pond to the Goto n , or delete
the Goto n if not required.
2 Store a program in program
area Prog “file name”, or delete
the Prog “file name” if not
required.
3 Correctly match “Next” with
“For”, “LpWhile” with “Do”, or
“WhileEnd” with “While”.
• Ensure that Prog “file name” is
not used to return from
subroutines to main routine. If
used, delete any unnecessary
Prog “file name”.
• Trace the subroutine jump
destinations and ensure that no
jumps are made back to the
original program area. Ensure
that returns are made correctly.
