Texas Instruments TI Programmable 57 User Manual

A FIRST LOOK AT THE
TI PROGRAMMABLE 57
In
the
example
you
considered
earlier,
when
you
press
RA),
the
machine
simply
pressed
its
own
buttons
and
doubled
the
display
value:
and
would
have
kept
on
doing
this
for
quite
awhile
—
had
you
not
stopped
things
after
21
“go-rounds”
with
the
P&lkey.
(As
you'll
see
later
on,
these
repetitive
go-round”
situations
in
your
calculator
—
and
in
larger
computers
—
are
called
"loops”’.)
At
this
point
you're
already
well
into
many
of
the
features
that
make
your
programmable
calculator
so
special.
Actually,
we've
explained
enough
here
so
that
you
can
now
explore
all
sorts
of
programs
on
your
own.
We'll
naturally
show
you
all
the
ins
and
outs
of
your
machine
with
more
on
how
to
solve
problems
and
run
programs
using
it,
later
in
the
manual.
But
don't
be
afraid
to
explore.
There's
really
nothing
to
it,
and
you
can’t
hurt
the
calculator
by
pressing
any
combination
of
buttons.
Your
calculator
can
be
easily
programmed
to
run
through
any
set
of
keystrokes
(up
to
50
steps)
which
you
could
handle
manually
from
the
keyboard.
Just: Push {tRa)
eEnter your keystrokes
(You'll
need
to
use
RS]
as
your
last
step
if
you
want
things
to
repeat,
or
as
your
last
step
if
you
want
things
to
stop
after
one
time.
Also,
if
you
need
to
enter
a
number
midway
in
a
program,
or
want
to
see
some
intermediate
result,
just
put
an
k#)at
that
point.)
id
¢Press (tRN) again

At
this
point
you've

your
calculator.
