Any
LABEL
can
be
written
at
the
beginning
of
tape
to
easily
classify
the
tapes.
The
label
skip
function
readily
skips
the data
from
LABEL
to
the
first
EOB
code
skip.
Therefore,
the
undesig¬
nated
address
or
function
characters
can
be
used
as
LABEL.
In
addition,
the
modified
code
which
disregards parity
is
also
available.
EOR
code
at
the
next
of
LABEL
means
the
stop
point
of
tape
rewinding.
Where
storing
NC
tape
data
into
memory,
with
the
label
skipped,
the
memory
stores
the
data
between the
first
EOB
code
and the
next
EOR
code
.
must
not
be
omitted.
NOTE:
See

MISCELLANEOUS
FUNCTIONS
Slash
"/"
character
means
the
optional
block
skip
function.
This
code
must
be
surely
punched
out
at
the
head
of
block
(before
the
address
N
of
se¬
quence
number).
If
this is
punched
out
on
the
way
of
the
block,
this
function
is
disregarded
even
if
the
optional
block
Bkip
switch is
ON.
The
character
specified
on
2.1.2
Address and
Function
Characters
should
be
used
for
program¬
ming,
but
others
should
not.
Where
the
tape
vertical
parity
check
(TV
check)
is
made,
number
of
characters
in
a
block
must
be
even.
If
odd,
it
should
be
made
even
by
using
"SP"
character.
The
disregarded
characters
such
as
"BS,
Tab,
SP,
UC,
LC
and
Del"
should
be
avoided
from
the
significant
data
area,
if
unnecessary.
The
maximum
allowable number
of
characters
in
a
block
is
96.
The
disregarded
characters such
as
"Del,
BS
and
Tab"
are
not
included
in
them.
Therefore,
EOR
code
at
the
end
of
tape

eration#
is
stopped.
In
most
cases,
the
control
is
reset,
or

auto¬
matically.
As
the
details
