trying

Here'sasimple
programtoshow
you
that
you can
get
your
64Ctodo
things
with
out
knowing
all
about
programmingorBASICormachine
language.
First,
hold
down
the
SHIFT
key
and
press
the
CLR
HOME
key.
This
"clears"
(that
is,
erases)
the
screen.
Then
type
the
following
lines
exactlyasthey
appear.
Press
the
RETURN
key
after
each
line.
The
numbersatthe
beginningofeach
line
tell
the
computer
that
you
are
entering
a
program.
Pressing
the
RETURN
key
after
you
type
each
line
tells
the
computer
to
"save"
that
line
(that
is,tokeep
the
line in
the
computer's
memory).
After
you
have
finished
typing
line30and
have
pressed
RETURN
for
that
line,
use
the
SHIFT
and
CLR
HOME
keystoclear
the
screen
again.
Then
type
RUN
and
press
RETURN,
and
follow
the
computer's
instructions.
If
you
get
any
kindoferror
messageonthe
screen,
you
have
probably
madeatyping
mistake.
Just
clear
the
screen
(use
SHIFT/CLR
HOME)
and
start
again.
There
are
many
prepackaged
software
programs
that
you can
use
with
not
much
more
experience
thanittakestouse
this
little
sample
program.
Once
you
"load"
suchaprogram
("loading"
means
putting
the
programinthe
computer's
memory),
the
program
instructsor'prompts"
you
about
whattodo.
The
sectioninthis
booklet
called
using
software
tells
you
how
to
"load"
and
"run"
prepackaged
software
programs.
If
you
are
interested
in
learning
howtocreate
and
run
your
own
programs
using
the
64C
and
the
BASIC
programming
language,

about
ram
and
rom
You
have probably
read or
heard
the
terms
RAM
(Random
Access
Memory)
and
ROM
(Read
Only
Memory)
usedinconnection
with
computers.
These
terms
refer
to
the
two
typesofmemory
usedbya
computerinprocessing
information.
RAMismemory
that
you
can
use
AND
change.
For example,
you can
use
RAM
to
enteraprogram,
and
you can
change
that
program
whileitisinRAM.
The
64C
can
hold
about
64,000
characters
(bytes)ofinformation
in
its
RAM.
This
memory
canbedirectly
usedbyyou,
anditcanbechangedbyyou.
ROMismemory
that
can
onlybeusedbythe
computer
itselftoperform
and
con
trol
its
internal
activities.
ROM
cannotbechangedbyyou,
although
there
are
methods
that
you an
usetosee
what
values
areinROM.
Your
64C
also
has
20K
of
standard
ROM
(Read
Only
Memory).
The
computer
keeps
trackofhow
much
RAM
you
have
used
and
how
much
you
have
left.
The
computer
also
keeps
trackofthe
contents
and
statusofROM.
So,
unless
you
are
interested
in
creating
your
own
programs,
you
generally
need
not
be
concerned
about
RAM
and
ROM.

Softwareisa

(also
calledaprogram)
that
tells
your

just
what

There
are
two
kindsofsoftware:
1.
Prepackaged

Prepackaged

called
"canned"
software.
You

There
are
many
thousandsofprepackagedor"canned"

Muchofthis

comes
from
commercial
software
companies,
but
there
are
also
many
ready-to-use
software
programs
availableincomputer
magazines
or
from computer
user
groups.
2.
User-Created
Software—
Thisissoftware
that
you
yourself
make
up.
To do
this
you must
use
a special
lan
guage,
known
as a
programming
language.
The
Commodore
64C
comes
with
a
built-in
programming
language
knownasBASIC
2.0;
see
the
SYSTEM
GUIDE
for
instructions
on
programminginBASIC

There
are
also
many
other
program
ming
languages
available
for
the
Commodore
64C,
including
LOGO,
PILOT,
LISP,
PASCAL,
etc.
