are
used
for
the

Data

punched

to
be
read
by
any
paper

reader
that
has
an
adjustable

The

reads
the

an

recording
the

that
are
on
the

as
5

The

are
recorded
as

interfaced
to

the

software
converts
the

into

for
entry
in

The
start
code
for
the

is
a
left
parenthesis,
(Figs

and
the

A
paper
tape
generated
by
a
programmer
contains
a
5-byte,
arrow¬
shaped
header
followed
by
a
null
and
a
4-nibble
byte
count.
The
start
code,
an
8-bit
rubout,
follows
the
byte
count.
The
end
of
data
is
signaled
by
two
nulls
and
a
2
-byte
sumcheck
of
the
data
field.
Refer
to
Figure
D-4.
If
the
data
output
has
a
byte
count
GREATER
than
or
equal
to
64K,
an
alternate
arrow-shaped
header
is
used.
This
alternate
header
(shown
below)
is
followed
by
an
8-nibble
byte
count,
sandwiched
between
a
null
and
a
rubout.
The
byte
count
shown
here
is
40000H
(256K
decimal).
If
the
byte
count
is
LESS
than
64K,
the
regular
arrowhead
is
used
instead.
Data
that
are
input
using
Formatted
Binary
format
will
accept
either
version
of
this
format.

In

a
third
variation
of
this
binary
format
is
accepted
on
download.
This
variation
does
not
have
an
arrowhead
and
is
accepted
only
on
input.
The
rubout
begins
the
format
and
is
immediately
followed
by
the
data.
There
is
no
byte
count
or
sumcheck.
