"Allow
me
to introduce myself."
Now
we'll
tell the Computer to execute our
program.
The BASIC command
for
this is
simple;
RUN. So type
RUN
and press
l^m:l
.
If
you made no mistakes,
the display will
read:
HELLO
THERE. I
AM
YOUR
NEW
TRS-80
MICROCOMPUTER!
If this
isn't what you
got,
go back and try it again. If HUN still doesn't
produce the greeting,
there's
something wrong in your program.
Type
NEW
to
clear
it out and type in
the one-line
program
again.
If
it
did
work
—
let
out
a
yell!
"HEY MA, IT WORKS!" This is very
important,
because now
that you
have tasted success
with
a computer, it may be the last
you are heard from
in
some
time.
Note that
the
word PRINT
was not displayed, nor were
the quotation
marks. They are
part
of the
program's
instructions and we didn't intend for them
to be printed.
Type the word RUN again and hit
IJt'Md;!
,
Type RUN to your heart's content, watching the
magic machine
do as it's told, over and
over. When you
feel
you've really got the hang of all this, get up and stretch,
walk
around
the room, look out the window
—
the whole act. Because you'll
soon get hooked and you
won't want to take time for such things later
on.

anything.
Maybe you're
wondering what's the
difference
between BASIC
commands
and BASIC
statements.
Commands
are
executed as
soon as
you
type
them in and press
IJ^fct3;l .
State-
ments are put
in
to programs and are
only
executed
after you type
the command
RUN
.
i
I
"HEY MA, iT
WORKS.'"
Whether
you're typing in a program; . or:
giving
direct
commands like RUN, you've got
to hit
ldhi£1j
to tell the Computer to take
a
look
at
what you've typed and
act
accordingly.
Special
message for people
who can't
resist the
urge
to
play
around with
the
computer
and
skip
around in this
book.
(Viere always are
a few!)

to "lose
