Interrupting a Running Program
You can interrupt a running program at any time by pressing
Å
or
¥
. The
program completes its current instruction before stopping. Press
¥
(run/stop) to
resume the program.
If you interrupt a program and then press
t
,
¹ r
, or
º Ô
, you
cannot resume the program with
¥
. Reexecute the program instead (
t
label).
Error Stops
If an error occurs in the course of a running program, program execution halts and
an error message appears in the display. (There is a list of messages and
conditions in appendix F.)
To see the line in the program containing the error–causing instruction, press
¹
£
. The program will have stopped at that point, (For instance, it might be a
÷
instruction, which caused an illegal division by zero.)
Editing a Program
You can modify a program in program memory by inserting, deleting, and editing
program lines. If a program line contains an equation, you can edit the
equation — if any other program line requires even a minor change, you must
delete the old line and insert a new one.
To delete a program line:
1. Select the relevant program or routine (
¹ r
label), activate program
entry (
¹ £
), and press
Ø
or
×
) to locate the program line
that must be changed. Hold the cursor key down to continue scrolling. (If you
know the line number you want, pressing
¹ r Ë
label nnnn moves
the program pointer there.)
2. Delete the line you want to change — if it contains an equation, press
¹
¡
{

}; otherwise, press
~
. The pointer then moves to the preceding
line. (If you are deleting more than one consecutive program line, start with the
last line in the group.)
