(A)
For
the
purposes
of
heading 8471,
the
expression
"automatic
data
processing
machines"
means:

the
execution
of
the
programme;

being
freely
programmed
in
accordance
with
the
requirements
of
the
user;
(3)
performing
arithmetical
computations
specified
by
the
user;
and
(4)
executing,
without
human
intervention,
a

them
to
modify
their
execution,
by
logical
decision
during
the
processing
run;

of
a
variable
number
of
separate
units.
Subject
to
paragraph

below,
a
unit
is
to
be
regarded
as
