"Why
didn't
the
word
END print?"
Answer:
Because
nothing is printed
unless
it is
the
"object"
of
a
PRINT
statement. So
how could we
get the Computer to print
THE END
at
the
end of the
program
execution?
Think for a
minute
before
reading
on.
98
PRINT
"
THE END
"
Erasing
Without
Replacing
Just for fun,
let's
move the END
statement from
line
99
to the largest
usable
line
number,
32767. This
requires two steps.
The
first is to erase
line
99.
Note that
we're not just
making
a change or
correcting
an
error
in line
99
—
we
want
to
completely
eliminate it from
the program. Easier
done
than
said:
Type:
99
Then
nana
The line is erased.
How can we
be
sure? Think about
this now. Got it???
Sure
—
"pull" a
LIST
of
the entire
program
by typing
list
BZQ3D
The
screen
should
show
the program
with lines
5, 10,
15,
20
and 98.
.99
should
be
gone.
Any
entire line
can be
erased
the
same way.
The second
step
is just as easy.
Type
32767 END
MJHHil
. . . and
the new
line
is entered.
Pull
a
listing of the program to
see if it was. Was
it??? Now
RUN the
program to see
if moving the END
statement
changed
anything.
Did it??? It
shouldn't have.
Other
Uses
for END
Move END from
#32767
to line
#17,
then
RUN.
What
happened?
It ENDed the
RUN
after
printing line
10
and a
space.
RUNit several times.
Now
moveENDto line 13
and
RUN . Then to
line 8
and RUN. Do
you see the effect
END
has,
depending where it is
placed
(even temporarily)
in
a
program?

This
will
work if
line
#98 is th&
last
PEINT
statement
in yautprc^raKi.
