verify
card has been
fed, correction card punching cannot
be done; however,
the corrected data
is
in
output
storage,
to
be used
if
there
is
a verify-duplicate operation
in
the
next
verify card.
MULT
PCH
Similar to
its
use
in
punching,
MULT
PCH
may
be used
in
verifying to verify a combination
of holes
that are not
represented
by
a single alphabetic or numeric key on
the
keyboard.
Press
and
hold
MULT
PCH,
and key
the neces-
sary
keys
(normally
digits
12-9) to
verify the
MULT
PCH
character.
When
MULT
PCH
is
released, verification occurs.
If
it
compares,
the operation continues;
if
it
does not
compare, an
error
is
signaled
by
the
VERIFY
light.
Note
that pressing
MULT
PCH
places
the keyboard
in
numeric
shift; also,
with
MULT
PCH
held
down,
the
-LZ
key
verifies
an
1
1 -punch
(via
input
storage) in the card.
REL
Use
of
the
REL
key
in verifying
is
an interruption of
the
verify process, and
the card cannot be
OK-punched
with
a
2-punch and
a
3-punch
in
column
8
1
,
except
by
refeeding
and
reverification.
REL
is
used to interrupt
verification
when
there are
numerous
errors in the
card, or
when
a
correction
is
improperly made, and
the
complete
correction
card punching
routine
is
not
necessary.
Pressing
REL
causes the
IBM
129
to ignore
all
following
data
in
the record
in
input storage, except
that
programmed
automatic ver-dup
fields
are verify-duplicated,
if
AUTO
SKIP/DUP
is
ON.
After
a
card has been
released,
use
FEED
or
CLEAR
to
continue
the operation.
(FEED
allows
verify
duplication
in
the next
record;
CLEAR
does
not.)
The
VER
CORR
key
does not
cause
a correction card to be punched,
because
a released card
is
an incomplete,
interrupted-verify
condition.
Frequently an
error
is
keyed
incorrectly
by
the operator,
and
neither
a correction-card nor a correction-verify
is
desired. In this case,
character backspace before
a
rewrite,
make
the correct
verification,
and
continue.
PROGRAM MODE
The program
card
is
loaded into storage
by
a
program
load
operation, described
in
Section
3.
A
single
program
at a
time
is
loaded.
The
program remains
in storage until the
mainline switch
is
turned off or
until
another program
load
operation takes
place for that
dial setting
of
PROGRAM
MODE.
The
operator can
shift
between program
levels
any
number
of times while entering data, through the use of
PROG
SEL,
followed
by
the
appropriate data key
(0-6).
The
card
punch
returns to the
program
level
indicated
by
PROGRAM MODE
on
advancing
from
card columns 00-01,
except
when REC
ADV/CARD FEED
is
set
to
MANUAL,
and
PROG
SEL
is
used to
set
the program
level for
column
01 of
the
next
record.
The
PROGRAM MODE
switch positions (other than 0-6)
are:
STAT
PCH:
This function provides
for
punching
out
production
statistics
data.
See
"Special Features"
in
Section
7.
PROG
PCH:
Pressing
REL,
with
REC ADV/CARD FEED
set
to
MANUAL,
followed
by
pressing
PROG
SEL, and
pressing appropriate data
keys
1-6,
with
a
blank
card
registered
at
the
punch
station, causes
punchout of
the
appropriate
program
level
from
storage.
See
"Punchout
(Stored Program)"
in Section
3.
Backspace and Rekey
The normal
verify
procedure
is
to
use
VER
RES
and
the
two-try-verify procedure
for verify corrections. If you do
not
want
to
make
the correction
(third) keystroke, using a
character/field/record
backspace
to reset the
error condi-
tion allows
you
to retry the
field
or position
again,
with
a
new
error retry sequence. Thus,
by
character backspacing
after
each second attempt,
endless attempts
to verify a
character can be made.
DATA
READ: When
READ
is
pressed, a
register
cycle
and
a card read cycle occur. This causes
a data
transfer
from
a
card
at
the read
station to
output
storage.
The program
is
automatically
set
to
program
level 0, so
this
data
can be
manually
duplicated and
new
data keyed
in
on
a selected
column
basis.
(This allows easy card makeover.) This
dial
setting selects
program
level
operation
for the
next card
in the data card recorder.
If a card
is
registered at either
station
when
READ
is
pressed, the read cycle does not
occur.
