Check the input numeric value and
correct it.
When using memories, check that the
numeric values stored in memories
are correct.
4Try using a smaller value for ∆ x
(x increment/decrement).
1Correctly input a Lbl n to correspond to
the Goto n, or delete the Goto n if not
required.
2Store a program in program area Prog
"file name", or delete the Prog "file
name" if not required.
3Correctly 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 un-
necessary Prog "file name".
• Trace the subroutine jump destina-
tions and ensure that no jumps are
made back to the original program
area. Ensure that returns are made
correctly.
• Simplify the formulas to keep stacks
within 10 levels for the numeric values
and 26 levels for the commands.
• Divide the formula into two or more
parts.
