Simple
Join Characters.
As
an
example
in
using the
formula
to
compute
simple
joins,
assume
that
you
wish
to
display
the following simple
join:
It
=
(6
X
0)
+
(2
X
1)
+
1
+32
=
(
)
+
(
2
)
+
1+32
=
35
10
Referring to the
ASCII code
chart,
you
will
see that
sending
the
ASCII code
for
the
#
(35 10
)
character
will
display the
ruling
character
shown
in
the example.
Complex
Join Characters.
For
complex
joins,
the
com-
puting
system
is
slightly
modified,
in
that
the
ruling
type
codes
are
modified,
and
the types of
joins are limited.
The
following
are
examples
of
those types of
complex
joins
NOT
present.

Jl
The
rule for
whether
a specific join exists
or
not
is:
A
HIGHER RULING TYPE
MAY
NOT TERMINATE
IN
A
LOWER
RULING
TYPE.
For
complex
joins,
the
P element
of
the
formula
is
always
given the value of three
(3),
the
S
element
states
the
join
type
of the
inferior
element,
and
the
T
element
is
the
orientation of
the
superior element.
T
=
(when
superior
element
is
horizontal)
T
=
1
(when
superior
element
is
vertical)
