Note
that
HOME
and
EE
are
in
the
current
path,
as
they
were
when
SP1
was
the
current
directory,
but
SP1
doesn't
appear
now. As a re-
sult, you
can
still find
the
variables
in
HOME (such as RENAME)
and
in
EE
(such as EQ1),
but
not
the
variables
in
SP1 (EQ, R1, R2,
and
R3);
now
you
can
create
new
variables
Rl,
R2,
and
R3.
Step
2:
Define
the
same
expression to
be
EQ.
As before, use STEQ to store
the
name
EQ1 in
the
variable EQ.
