Now you

also).
Many
computer
users
make a
second
or
even a
third
recording of
the tape,
just to be
sure they
have a good
recording.
NOTE: To
load the
full
4K
of
RAM
in
the TRS-80
takes less
than
3
minutes of
tape.
Short programs
will
take only a few
seconds
of
tape.

CTR-41 's
Tape

For best
results,
use Radio
Shack's
special
10 minute
Computer
Tape
Cassettes
(especially
designed
for
recording
computer pro-
grams).
If
you
use
standard
audio
tape
cassettes,
be sure to
use
top
quality,
such as
Realistic
SUPERTAPE.
Keep in
mind
that
audio
cassettes
have
lead-ins
on
both
ends
(blue
non-magnetic
mylar
material)
—
you
can not
record
on
the
leader
portion
of the
tape.
Advance
the tape
past the
leader
before
recording a

One
More
Thought
-

')".;
:
You're
all
ready
now,
right?
Well, maybe.
But let's
just
prepare
you
for
the TRS-80
and
Manual
with
one
more
thought
.
.
.
How
do you
"talk" to a
Computer?
In
Binary
Numbers?
In
Elec-
tronics
(is there
such a
language . .
,)?
In
English
. .
.?
Well,
we
use a
simplified
form
of
English
—
it's
called
the
BASIC
Language
(Beginners
All-purpose
Symbolic
Instruction
Code).
(There
are lots
of other
"computer
languages", but
this is
the easiest.)
This
Manual
covers
Radio
Shack's LEVEL I
BASIC.
As you go
through
this
Manual
you'll learn the
different words of
this
simple
computer
language
—
and how to
punctuate
(VERY
IMPOR-
TANT)
—
and
how to
apply
all of it for fun
and
practical benefit.
It's
an easy
language
to
learn
—
but remember,
you've got to
use
the
language
that the
TRS-80
understands
(well
be
giving you
some
examples
of
wrong
language
use and
you'll
see
what happens).
