(b).
When
M
codes
for
rewind
(M02
or
M30)
are
used,
the
program
returns
to
the
initial
address.
When
M
codes
for-
reset
are
given,
the
following
program
is
executed
as a
main
program.
NOTES:
"Subprogram"
simply
means
the
program
spec¬
ified
by
M98
command.
Therefore,
no
special
consideration
is
required
for
storing
and
edit¬
ing
of
subprograms.
•
M98
cannot
be
used
in
a
subprogram
more
than
8
levels.
Even
when
the
program
copy
(G25)is
used
in
combination,
the
limit
is
8.
If
more
than
8
levels
are
programmed,
an
alarm
code
"15"
will
be
displayed.
Signals
M98
and
M99
are
not sent to
the
ma¬
chine.
•
The
sequence
number
designated
by
the
address
P
is
searched
from
the
first
address
of
memo¬
ry
and
the execution
of
program
starts
from
the
first
block
of
the
sequence
number searched.
Therefore,
the
same
sequence
number should
not
be
used.
-
When the
sequence
number
designated
by
the
address
P
is
not
found,
it
causes
an
error.
•
Addresses
P
and
N
designate
sequence
num¬
bers.
Up
to
four-digit
number
can
be
used
for
sequence
numbers
and
leading
zeros
can
be'
suppressed.
•
The
sum
of
the characters
of
the
main
program
and
the
subprogram
should
not
exceed
the
mem¬
ory
capacity
of
the
control.
•
Address
L
cannot
be
used
together
with
M99
command.
•
The
remaining
number
of
repetitions
of
a
sub¬
program
is
displayed
when
POS
key
is
depress¬
ed,
the
address
L.
is
set
on
the
address indica¬
tor,
and
"01"
through
"08"
is
set
as
NUMBER,
during
the
operation
of
repeating
command
P.

-The
digit
set
as
NUMBER
means
the
number
of
levels
that the
subprogram
has
been
run.
•
Subprograms
cannot
be
executed
by writing
M98
in
MDI
mode.
•
•
Perpetual
program
runs
are
possible
by
using
M99
command
in
a
main
program.
When
the
RESET
button is
depressed,
the
program
re¬
turns
to
the
first
address
of
memory.

M98
command
from
punched
tape
M98
may
be
given
from
punched
tape
to
jump
to
a
subprogram.
In
this
case,
all
the
subpro¬
grams
to
which
jumps
are
to
be made
must
be
stored
in
the
tape
memory.
After
a
jump
has
been
made
to
a
subprogram
in
the
tape
memory,
the
rules
governing
the
subprograms
as
describ¬
ed above
take
effect.
After
executing
the
sub¬
program,
the
program
returns
to
the
block
that
follows
the
jump
instruction.
NOTES:
*
•
After
the
subprogram
runs,
the
program
returns
to
the
punched
tape
and the

Simple
jump
command
M99
cannot
be
given
from
a
punched
tape.
If
given,
it
is
neglected.
•
If
an
M
code
involving
rewinding
M
code
(M02
or
M30)
is
given
in
a
subprogram
to
which
a
jump
is
made,
the
