GETTING
STARTED
As
you
can see this keyboard
is
divided into tour sections:
• a
row
of eighteen function keys
at
the top of the keyboard
•
an
alphanumeric keyboard similar
in
most respects to a normal
typewriter keyboard
• a numeric keypad
• cursor control
key
section
A WARNING ABOUT NUMBERS
Numbers appear both
in
the alphanumeric section and the numeric
keypad and can
be
keyed
in
from either. The system is not concerned
where the numbers come from, providing that it gets a number when
a number
is
required. (Exceptions
to
this general rule are documented
with the applications
in
which such exceptions occur.)
In
ordinary typing you can use a lowercase I or
an
uppercase I tor the
digit
one.
Similarly, you can use
an
alphabetic O for the digit zero.
If
you
do this with a computer the results are unpredictable.
Always use numeric keys for one and zero.
USING THE KEYBOARD
For
the entry of text or data, the system keyboard can be used
as
a
normal typewriter, once the appropriate program has been loaded.
However,
when it comes
to
using the keyboard to communicate with
the system -
to
tell
it,
tor example, that you have finished entering a
command - then one of the special keys has to
be
used. The following
sections describe some of the functions performed by the special
keys
.
For
ease of reference, this material is listed
by
function, rather than
by
key.
Where differences exist between the two keyboards, these will
be
noted.
