— THE
RUN/STOP KEY
(2ed) GS — THE
PAUSE KEY SEQUENCE
— Tre Run/Srop Key
Pressing
the
key
(when
out
of
“learn”
mode)
tells
your
calculator
to
start
running
a
program
(from
the
current
location
of
the
program
pointer).
If
a
program
is
running,
pressing
this
key
(and
holding
it
momentarily)
tells
it
to
stop.
The
R&S)
key
has
a
dual
function
—
if
things
are
stopped,
it
starts
them
going;
if
a
program
is
running,
it
stops
it.
The
4)
key
can
be
used
as
part
of
a
program,
too
—
when
entered
in
“learn"'
mode.
If
a program
is
running
and
it
encounters
an
instruction
as
a
program
step,
it
simply
stops
and
displays
whatever
is
currently
in
the
display
register.
This allows
you
to
stop a program
to
see
intermediate
results,
to
enter
new
numbers
the
program
may
need
to
work on,
or
to
halt
the
action
when
the
program
is
finished.
Note that when you're out of “learn” mode and press , the program
pointer
begins
stepping
through
program
memory
starting
from
its
current
location.
If
you
want
to
start
at
the
first
program
step
(step
00),
you
need
to
press
before
pressing
IRA).
(You
can
position
the
program
pointer at any other location you'd like to start at with the key —
discussed later.)
[2nd] — Tue Pause Key SEQUENCE
This
key
sequence
is
designed
to
be
used
as
part
of
programs,
and
you enter it into your program while in learn" mode. While a program is
running and the program pointer comes to a [2a] HMM instruction, it stops
the program for about % of a second and displays whatever result is in
the display register at that point. Then, it continues on to the next step.
The QB key sequence lets you get a quick look at a program result,
without stopping the action. This sequence is especially handy when
used in repetitive programs (or "loops’’) — letting’you watch the
changing results of continuing calculations. You can watch your money
grow" in a compound interest account as the months go by, or watch a
function go to a ‘limit’, etc, If you'd like a pause that's longer than % of a
second,
you
can
just
add
additional
2s)
MIB
key
sequences,
and
keep
things in the display % of a second longer for each pause sequence you
add. (Keep in mind, however, that each MM key sequence you add
to a program will use up one of your 50 allowed program steps.)
