Radio Shack Telephone Interface II Manual

PROGRAMMED
CALCuMilQNS
•
You
program
your
TRS-80
using
a
computer
language
called
BASIC.
BASIC
is
generally
considered
the
easiest
computer
language
to
understand
—
since
it
uses
simple
English
words.
But
of
course
BASIC
is
not
limited
to
beginners
—
it
is a
very
powerful
computer
language
used
by
many
experienced
professional
programmers.
You
can't
"talk"
(or
"type")
to
your
Computer
in
an
every-
day
English
conversational
manner.
You
have
to
use
the
correct
words,
in
the
correct
sequence
that
is,
according
to
certain
rules.
With
a
Computer,
you
are
the
master,
you
are
the
boss.
The
Computer
can
only
do
what
you tell
it.
But
you
must
give
the
instructions
in
a form
the
Computer
can
understand.
That's
where
the
BASIC
language
comes
in.
Each
BASIC
instruction
must
start
with
a
line
number
(normally
we
start
with
10
and
each
successive
line
is
by
10's
—
10,
20,
30,
etc.).
Since
this
Manual
is
not
intended
to
be
a simple
learner's
guide
to
BASIC
Programming,
if
you
feel
we
are
moving
along
.too
fast,
we
urge
you
to
stop
by
your
local
Radio
Shack
store
and
obtain
a
copy
of
either
(or
both)
of the
following
books:
BASIC
Computer
Language
(60-2016)
BASIC
Computer
Programming
(60-2015)
