Check column
indicator;
decide
what
type of backspacing
(character,
field,
word,
or record)
is
required to
correct
the
error.
Then
backspace
accordingly,
and
rekey
the
data. (All
keying
is
done
in
erasable storage,
before automatic punching.)
If
column 80
is
keyed
with
REC ADV/CARD FEED
set
to
AUTO,
the card
is
punched
immediately
after
keying
column 80
before the
error
is
noted;
therefore, the
card
must
be
repunched.
Press
(VER)
DUP
until
the
column
indicator
shows
the
start
of
the
last field.
Rekey
the
last field.
This
punches
a
new
card.
(Dispose
of
error card
in stacker.)
Note:
For
control
of column
80,
set
REC ADV/CARD FEED
to
MANUAL;
the
column
indicator stops
at
00.
Operator
may
character
(or
other)
backspace
into
the record
if
a
correction
is
necessary,
or
program
select
to cause
punchout,
or
set
REC ADV/CARD FEED
to
AUTO.
If
red
VERIFY
light
is
turned
on and
the
keyboard
locks,
press
VER
RES.
The
light
is
turned off
and
the
keyboard
is
unlocked.
Rekey
the
doubtful
character.
If verify
error again
is
indicated, press
VER
RES,
and
the next
rekey
automatically rewrites the
error character.
Now,
character
backspace
and
reverify that character.
At
completion of
record, the
column
indicator
shows
CC
for
operation
intervention.
Manually
insert
a
blank
card
at
the
punch
station
and
press
VER
CORR.
The
card
is
automatically
punched
with
corrected
data,
and punched
with
a
2-punch
in
column
81,
to indicate
it is
a "correction"
card.
Specific
field(s)
coded
for
auto dup, operating under
program
control,
with
AUTO
SKIP/DUP
set
to
ON.
Punch
Mode:
Writes
the
same
data
as
in
the
previous
record.
Note: Auto-dup
operates
o^er
blank
columns
in
numeric
fields.
Verify
Mode: Compares
data
in
present record
with
the previous record
data,
and
signals
an
error
if
the
result
is
a
no-compare, then
reverts
to
a
manual
field.
Note:
Auto dup
is
not
active after a clear
operation, or
on
the
first
record
of
a job,
until
master data has
been
read
in
or
keyed
into
output
storage.
Following procedure
in
"Dup
Field,
Punch
(Manual)",
duplicate
all
columns
that are correct,
up
to
column(s)
to
be changed
(if
any).
Key
changed
data;
manually
duplicate the
remainder of
the
card.
Pressing
DUP
causes data duplication
from
the
last
card
(whose
data
still
remains
in
output
storage) to
this card.
Under program
control the
entire
current
field
is
duplicated;
without program
control
one column
is
duplicated.
The
DUP
key
has a
repetitive
action
and
operates
at
10
columns/second
in
program
level
0,
or
10
fields/second
in
program
levels
1-6.
The
procedure
is
generally
the
same
as in
punch
mode
(see
"Dup
(Automatic)", except
that, in
an
LZ
programmed
field,
DUP
is
active in
the high-order position
of
the
field
only.

the
field
has
been
programmed
for alphabetic
punching, such
as
a

field,
key
the alphabetic entry, press
BLANK
COLUMNS/LEFT ZERO
CTRL.
This
right-justifies
all
field
entries for that
alphabetic
field,
and
inserts
leading
blanks to the
left
of
the data.
If
the
field
is
programmed
numeric,
and
left

are desired,
hold
down
ALPHA
while
you
press
the
