Verify
Mode
Key
verification
of
self-check
fields
is
not normally done.
Verification
of
self-check
fields
can be accomplished
for
cards
not
originally
punched on
a
machine with
the
self-check feature,
thereby
assuring
both
the
verification
and
self-check
digit validity.
A
card OK-verified
without
errors
overpunches
the
1
1
-punch
in
column
81
in
addition
to the
normal
(2-
and
3-)
punches
in
column
81
In verify
mode,
fields
programmed
for
both automatic
skip
and
SC, with
the
AUTO
SKIP/DUP
switch
ON,
perform
the self-check calculation during the skip opera-
tion. If
an
error
exists,
the
IBM
129
stops
in
the
units
position,
and
operator intervention
is
required for continua-
tion
of
verify
by
use
of normal
verify self-check
procedures.
An
all-blank
field results in
a self-check
error.
With
AUTO
SKIP/DUP
turned
OFF,
normal
key
verification
is
required.
If a
VER CORR
key
rewrite
is
done
in
a
self-check
field,
the
SC
calculation
is
not performed during
the rewrite
operation;
it
is
done
only during
reverification
of
the
corrected
number.
During
verify
mode,
a self-check error
occurs
when
the
machine-calculated
self-check
digit
does not
agree
with
the
check
digit
read
into
input
storage
from
the
card,
Note
that
the
keyed
units position
digit
is
not used
by
the
machine
for
comparison.
However,
it
must
be
keyed
to
initiate
the
comparison of
the
check
digit in
the card
and
input
storage,
(or
in
input
storage alone,
if
a correction
was
made
in
input
storage)
and
the
machine-calculated
check
digit.
The
machine-calculated
check
digit
is
based
on
the
verified
digits
in
input
storage.
All errors identified
in
high-order positions
of
a self-check
field
are verify errors
and must be handled
accordingly;
all
errors
in
the
units position
of
a
self-check
field
are
self-check
errors
and
may
be handled
by
one of
the
following procedures.
(Note
that the
SC
error indicator
turns on,
and
the
keyboard
locks
when
the units position
is
keyed.)
Procedure
1-Blank
Out
the
Field
1.
Press
FIELD
BKSP.
2.
Press
VER
CORR.
3.
Press
SKIP
(inserting
blanks
in
buffer;
keyboard
locks
for reverification).
4.
Press
FIELD
BKSP.
5.
Press
SKIP
(reverification
operation).
6.
Continue normal
operation.
The machine
is
set
for
a
verify-correction-card
punchout
at
the
end of
this card.
Appropriate
escape
procedure can
override the correction
punchout.
Procedure 2-Verify an
Overpunched
Error
Field,
Exactly
as
Keyed
1
Press
VER
SC
(unlocking the keyboard).
2.
Hold
down
MULT
PCH
(which
rests
the
self-check
condition
and
allows
normal
verification
of
the units
position
of
the
field),
and
3.
Press
12 (&)
or
1
1
(—
)
key and
the appropriate
digit
key.
4.
Continue normal
verify
operation.
Unless
storage
was
changed
via
some
other
correction, a
verify-correction-card
punchout
is
not
set.
Column

Status,
Procedure
2:
1.
Error Card:
Condition not
set;
if set,
no
punching
occurs.
2.
Current Card:
Receives OK-verify
identifier
(2-
and
3-punch);
1
1-punch
is
prevented even
if
there are other
valid
SC
fields.
3.
Correction Card:
If
condition
is
set,
receives verify-
correction
identifier
2-punch;
1
1-punch
is
prevented,
even
if
there are
other
valid
SC
fields.
Procedure 3-Correct
the Self-check
Field
Note
that high-order positions are corrected
by
normal
verify-correction
procedures
prior to
reaching the units
position error
indication.
Procedure
3
may
also
be used
to correct the
entire
field
or
add
the
number
to the record,
if
procedure
A
was
used
in
punching,
and
the
field
in
the card
is
blank. In
this case,
press
VER CORR
at
the
start
of the
field,
and perform
a
normal
verify correct,
and
reverify
procedure.
Note
that
during
the
VER CORR
rewrite
of
the
field,
the
SC
calculation
is
not performed;
it
is
only performed during
the
reverification
of
the
field.
To
correct
the
units position:
1
Press
VER
SC
(restoring
keyboard;
light
remains
on).
2.
Press
VER CORR
(resetting self-check
condition).
3.
Key
the
self-check
digit
(units position).
Keyboard
locks;
light
is
turned
off;
column
indicator
shows
88;
reverification
is
required.
Since
this
was
a
VER CORR
rewrite,
no SC
calculation
occurred;
it is
necessary
to
reverify for
the
SC
calculation to
be performed.
4.
Press
FIELD/WORD BKSP
key.
5.
Reverify the
field.
6.
Continue normal
operation.
The
machine
is
set
for
a
verify-correction
punchout
at
the
end
of
this
card.
Appropriate escape procedures can
override the correction
punchout.
