"

to
al'ly
of
these
questions reread the p
r'
evious secti
on
to clear up the
problem.
Ok. one more thing and
you
arc
r
eady
to
go:
With the same comrnand which
saves
your
p1rog
ram you must gi
ve
the progr
am
a "fi lename".
Th
is is
for r
efe
ren
ce
purposes.
You
r filename can
not
be
longer than
16
characters.
To
s.ave
the program
with
a filenarne t
ype:
CSAVE 1

Your program wi

e name
"PROG
,.

You can assign
any
name you desire,
whotever is easi
es
t for you
to
keep
tr
ack
of.
Al
so
. note that there
is
a
16
cha
r
acter
length limit for
your filename. If the name
is
longer t
han
16
cha
racters, the excess is ignored. A good practice
is
to maintain a pro9ram 109, which includes t
he
prog
ra
m name, starting and st·oppi
ng
location
on
ta
pe
(use
tf\e
counter
numbers), and a brief descripti
6n
of
what
the
pro
gr
am does.
Press the
(
••m•
I key.
At
this ti
me
you
shoul
<l
hear a sh
ri
ll buzzing sound, a

d the tape should
be
turn
i
ng
. Also the " BUSY" indicator should light
up
.
TI

is
tells you
that
the
computer
is
"b

transf
er
ring
your
program from memory
to
the
tape.
If
th
is does n
ot
happen, s
tart
again
from
th
e beginning
of
th
e section.
It

tries
to
get it right. so
don
't
be
discourag•d.
If I can do
it,
you
can do it .
Once
th
e
compu
ter arrives
at
the e
nd
of
the
program, the "BUSY" indic
ator
li
ght will go off.
the recorder w i;
ll
stop, and the
"prompt"
will re -appear on the di
sp
l
ay
. Congratula

yo
ur fi
rs
t
Program has
be:en
saved
fo
r future
use
. In order to insure
that
this
has
in fa

been accom
pl
ished
we
can read
it
back i
nto
memory
from the ta
pe
as explained in the
next
section .
3. The CLOAD command
Now
t
hat
yo
ur first program
is
saved
on
ta
pe
,
you
will
no
doubt
want to
se
e if it is really ther
e.
To
do
this
is
relatively
si
rn
ple; use the CLOAD? comrnand, of course.
"What does it do?"
you
ask. Well.
after
CSAVEing your program simply
type
CL
OA
D? The
computer
compa
r
es
t
he
CSAVEd program wiith the one in i
ts
memory
.
If
all went
\ve
ll,
it will
calmly display yo
ur
f
il
ename and end its check.
If
a
ll
did
not
go
well. an
error
message will
be
displayed, usually ERROR
43
. This tells
you
that
the prograrn on tape is somehow different
from the program in SHARP's memory. Erase
tha
t p
ortio
n
of
tape
and
start
again. Check
all
your
connections. and try turning the volu
me
Jnd tone up a li
