Simple Programming
Whether the PRGM-RUN switch is set to PRGM or to RUN, when
you press
. nn, the calculator immediately jumps to the program
memory line number specified by the two-digit number nn. No
instructions are executed. If in RUN mode, you can momentarily slide
the PRGM-RUN switch prem[[[[Illlrun to PRGM to view this line of
program memory. If the calculator is already in PRGM mode, the line
number and keycode for the instruction contained in that line are
displayed. If you now press
in RUN mode, execution will then
begin with that line of program memory. Loading of new keystrokes
will begin with the next line of program memory.
Programmed Stops
When programming, there may be occasions when you want a program
to halt during execution so that you can key in data. Or you may want
the program to pause so that you can quickly view results before the
program automatically resumes running. Two keys,
(run/stop)
and
(pause), are used for program interruptions.
Stopping During Program Execution
The
(run/stop) function can be used either as an instruction in a
program or as an operation pressed from the keyboard.
When pressed from the keyboard:
1.
If a program is running,
stops the program.
2.
If a program is stopped or not running, and the calculator is in
RUN mode,
starts the program running beginning with the
current line in program memory.
When executed as an instruction during a running program,
stops
program execution after the current line of program memory. If
is
then pressed from the keyboard, execution begins with the current
line of program memory. (When
is pressed and held in RUN mode,
it displays the line number and keycode of that current line—when
released, execution begins with that line.)
You can use these features of the
instruction to stop a running
program at points where you want to key in data. After the data has
been keyed in, restart the program using the
key from the keyboard.
