of
Program
Memory
^
-,
When
loaded
with
programs,
the
program
memory
changes
as
follows:
An
input
is placed
(on
a
1-character
=
1-step
basis)
in
the
input
buffer,
when
ENTER
is
pressed
the
input
is
written
in
the
program
memory
(after
being
converted
into
the
form
of
1
-instruction
=
1-step).

One
line
of
a program
can
hold
a maximum
of
80 steps
(1
step
=
1
character)
Lines
are
stored in
numerical
order
into
the
program
memory
(even
if
not
entered
in
numerical
order).

However,
the real
program
memory does
not
have
a
separate
storage
area
for
every
line
as
shown
above,
but
stores
programs
step by
step in
a
row;
your
Computer
has
a
capacity
of
1424
steps.
