4A:
Oh
Pshaw!
And
it
seemed
so
easy.
You
should have entered:
55 A =
INK
1000
*A)/1000
Oh, you
did?
And
you got
3
answers, then
it
crashed, saying:
HOW?
55 A =
INK
1000
*
A)?/1000
It is all
correct.
Then
why
doesn't
it
work?
Well,
if
you have
LEVEL
II
BASIC
it
did
work.
If
you
can't figure
out
why
it
didn't
work
with
LEVEL
I
and
you
don't
know why, you
forgot to read the
NOTE
at
the beginning of
the
lesson.
Go
back and
read
it.
OK. 32727
is
the
largest
permissible
number
inside
the brackets of
INT(A).
When
the pro-
gram
tried
to
execute the fourth pass
of the loop,
it
hit
INT(1000 * 5(3.2654) etc.
which
becomes
INT(5(3265.4)
which
is,
of course,
too
big.
So
the
Computer
said
HOW?
But
wait
—
there
is
a
way
to get
the desired
result.
Try
55A
=
INT(A)
+
INK
{
A-
INK
A)
)
