Variables
There
are
three
types
of
variables:
local
variables,
common
variables,
and
system
variables.-
(1)
Local
variables
(
#
1
to
#
33)
Local variables
are
used-
locally
for
each
macro.
This
type
of
variable
is
such that
each
time
a
macro
is
called,
new
local
variables(
#1
to#
33)
are
independently
secured
for
that
macro.
In
this
case,
when
an
argument
is
specified,
the
value
of
that
argument
is stored
in
the
local
variable;
or
the
results
of
calculation
in
the
macro
are
stored
in
the local variable.
The
contents
of
the
local variable
are
empty
if
no
argument
is
passed
to
the
macro.
When
a
macro
returns
by
instruction
of
M99,
the
local variable
for
that
macro
becomes
blank.
Also,
When
the
equipment
is
turned
on
or
reset,
ail
local
variables
become
blank.
