Your
OL should be connected
to
a monitor screen or
TV
set
and switched
on.
Press
a
few
keys,
say abc, and the screen should appear as shown below
The
small
flashing
light
is
called the cursor.

If
your screen does
not
look
like
this read the section entitled Introduction. This should
enable you
to
solve any difficulties
The
OL
IS
a
versatile
and powerful computer,
so
there
are
features
of
the keyboard which
THE
KEYBOARD
you
do
not
need
yet.
For
the present
we will
explain
Just
those
Items
which you need
for this and the next
six
chapters.
This enables
you
to
'break' out
of
situations you
do
not
like.
For
example;
BREAK
a line which
you
have decided
to
abandon
something wrong which
you
do not understand
a running program which has ceased
to
be
of
interest
any other problem
Because BREAK
is
so
powerful
it
has been made difficult
to
type accidentally
Hold down
ICTRL Iand then press ISPACE I
If
nothing
was
added or removed
from
a program while
it
was
halted
with
BREAK then
it
can be restarted by typing:
CONTI
NUE
This
is
not a
key
but a small push button on the right hand side
of
the OL
It
is
placed
RESET
here deliberately, out of the
way,
because
its
effects are more dramatic than the break
keys.
If
you cannot achieve what
you
need
With
the break
keys
then press the
RESET
button. This
is
almost the same
as
switching the computer off and
on
again.
You
get
a clean
re-start.
