Line
•
Lines
must
be
numbered
with
integer
numbers
ranging
from
1
to 999.
•
Ending
of
a
line
is
accomplished
by
inputting
the
S
key.
The
ENTER
instruction
is
repre-
sented
by
a
space
in
the
display.
(Nothing
appears.)
Statement
•
One
line
consists
of
one
or
more
statements
(statement
instructions
in
the
BASIC
language).
•
Statements
are
divided
by
colons
(
:
).
Step
One
statement
consists
of
one
or
more
operation
instructions,
each
of
those
instructions
having
a
capacity
of
one
step.
Instructions
such
as
LIM,
SIN
and
INPUT
are
processed
as
one-step
information
written
into
the
program
memory,
even
though
represented
in
the
display
by
two
to
six
characters.
Label
Characters
(letters,
numerals,
symbols)
are
placed
between
quotation
marks
following
a line
number.
The
label
serves
as the
sign
for
a
program
jump,
etc. See
page
42.
Note:
Each
line
number
(1
through
999)
is
held
as
two-step
information
in
the
program
memory.
Although
not
present
in
a
program
memory,
the
colon
(
:
)
that
follows
every
line
number
is
automatically
displayed
immediately
after
programs
have
been
written
or when
they
are
recalled.
