INSTANT PROGRAMMING
(No Water Necessary)
This
section
is
devoted
exc
lusiv
ely
to a select group
of
people (the authors included) whose
inquisitiveness ou t
..
veighs their patien
ce
(and perhaps their
common
sense). For those
of
you
who
absolutely must
DO
SOM
ETHING w
it
h.
this miracle
of
modern electronics, we present
a
simple programming exercise. (WARNING: The timid
or
faint.of.heart
are
instr
uc
ted
to
proceed
to
Chapter
1;
Getting Acquainte
d,
for a more thorough
and
leisurely
in
tro
duc
tion
to
the
SHARP
PC· 1500).
Before you
pro
ceed, one further caution is in order. It
is
important to follow all
of
the
listed
steps
in
the
given
order. Contrary to popular
op
inion. conlputers arc not "super·brains" and
do
not
have
the
average human's abi
li
ty to "figure
out"
what
you
desire. The PC·1500 simply awaits
yo
ur
instructions
and
performs them. Are
you
ready? Good, let
's
begin.
Example 1
First, find the
key
marked
"ON"
in
the
upper
ri
g
ht
corner of
the
keyboard. Pressing this key
will cause
the
sleeping electronic genie to awaken (d
on't
expect a puff
of
smoke!}. The d isplay
portion
of
the computer should
be
similar
to
the illustration below:

the
upper

of
the display. (If you press the key
too
many times. just
pr
ess
it
again until
the
desired
result
is
obta
ined). The SHARP
PC
·1
500
is
ready
to
accept
the
series
of
instructions which make
up
a
computer
program.
Enter

Notice that as
you
press
the

you
have typed in.
The
display should now look I ike this:

OEG
PRO
Note: Throughout this manual we will use 0

the
number zero,
so
that
you
can distinguish
between
the
letter 0
and
the
number !l.
Continue
by
pressing the following keys.
Do
not
be alarmed when each l

disappears
as

This
