A
little
more
information
will
be
needed
to
complete
the
shape
table.
Shape
Table
Directory
The
shape
table
directory
contains
the
number
of
shape
defini-
tions
in
the
table.
It
also
points
to
the
starting
location
of
each
shape
definition. A maximum of
255
shapes
may
be
defined
in
a
shape
table.
The first
byte
of
the
shape
table
contains
the
number
of
shape
definitions
in
the
table.
The
second
byte
is
not
used. Starting with
the
third byte, a
table
of indices
is
stored,
which
references
the
starting addresses of
the
individual
shape
definitions.
