2. Writing
programs
When you "write" programs
using
the
keyboard,
set the Computer
in the PRO
mode.
Preparation
When writing
a
new
program, we
suggest
that you
clear the program
memory
by using
a NEW
command.
However,
this is not true
if
you
want to
write
a
program
in
succession
with
the
preceding
one.
[Procedures]

If
you
followed the Notes in the
chart,
you'll
realize that
the lines
of
instruction
are
first
held
in
the input
buffer
and then
loaded into
program memory when
you press
(^)
.
As you
enter
a
line into
the
Computer you
notice
that
a colon
appears
after the
line
number.
Also the Computer adds a space
after
commands
(PRINT,
INPUT, etc.).
If
any line contains
more
characters
than
the display
can show at
one
time, only the
beginning
portion of
the line
of instructions
will be
displayed
(up
to
24
characters
and spaces).
