Texas Instruments TI Programmable 57 User Manual

(ies) — THE
LEARN KEY
— THE
RESET KEY
— Tue Learn Key
Pressing
this
key
once
puts
your
calculator
in
the
“learn
mode
of
operation
—
ready
to
be
taught
a
program.
When
the
calculator
is
in
“learn”
mode,
the
display
takes
on
a
whole
new
format,
displaying
4
(and
sometimes
5)
digits.
00 00
The
leit
two
digits
in
the
display
will
indicate
the
step
number
you
are
about
to
enter
into
the
machine.
(You
can
enter
up
to
50
steps,
labelled
00
through
49.)
The
digits
to
the
right
are
for
key
codes.
These
are
two
and
three-digit
numbers
that
tell
the
calculator
which
program
steps
you're
entering.
These
right
two
digits
(and
a
3rd
one
that
will
pop
up
as
you
enter
certain
keystrokes)
will
be
zero
while
you
enter
a
program.
This
is
because
the
display
is
always
reading
out
the
step
you
are
ready
to
enter,
and
immediately
moves
to
the
next
step
location
in
program
memory
after
you
enter
a
step.
(Later
we'll
be
discussing
how
you
can
go
back
and
check
the
key
codes
for
each
step
you've
entered.)
Pressing
the
key
a
second
time
takes
your
calculator
out
of
“learn”
mode,
and
it's
ready
to
run’a
program
—
or
do
calculations
right
from
the
keyboard.
At
this
point
the
display
changes
back
to
its
standard
format.
Note
that
while
you're
in
“learn
mode,
the
calculator
won't
do
keyboard
calculations
—
it
will
interpret
each
keystroke
you
enter
as
a
program
step
to
be
stored.
Once
you've
stored
a
program
and
get
out
of
“learn”
mode,
you
can
do
any
keyboard
calculations
you
need
to
—
without
affecting
the
program
stored
in
program
memory.
Also,
note
that
turning
your
calculator
OFF
clears
the
program
memory
completely
(as
well
as
all
other
calculator
memories
and
registers).
[RST] — Tue Reset Key
This
is
the
“start
back
at
the
beginning”
key.
It
tells
the
program
pointer
to
go
back
to
step
00.
This
key
can
be
used
as
part
of
a
program
(you
can
enter
it
while
in
“learn'’
mode),
or
right
from
the
keyboard
when
out
of
“learn’’
mode.
When
encountered
as
part
of
a
program,
the
program
pointer
immediately
jumps
back
to
the
very
first
step
—
step
00,
and
keeps
on
going.
When
used
from
the
keyboard
when
out
of
“learn”
mode,
pressing
just
sets
the
program
pointer
to
step
00.
The
also
has
other
special
functions.
It
resets
the
subroutine
level
counter
back
to
zero
and
clears
the
subroutine
return
register.
