space without pressing the error reset key. Use the backspace
key on machines with the self-checking feature installed.
34, Rel (Release): This key is used to advance the card in
the read or punchstation through column 80. If the ma-
chine is under program control and the release operation
encounters an auto dupfield, the auto dup informationis
punchedbefore the release operation can continue. Thus,
when a card is released because of a keying error, the common
information is notlost.
Multiple release and register cycles are not required to clear
the card transport area of cards. Use the clear switch for this
operation.
35. Feed (Card Feed): The feed key, if held depressed, moves
two cards from the hopperinto the punchstation and prereg-
ister station. It is inoperative when a cardis registered at the
punch station.
36. Skip: A skip can be initiated manually by operating the
skip key. Skipping occurs at 80 columnsper second and con-
tinues to the end offield definition under program control,
or in theabsenceoffield definition, each key operation results
in a single space.

37, Reg (Card Register): When a single card is fed from the
hopper, or when a card is manually inserted at either the
punchor read station, operating the register key locates the
card in the proper position for reading or punching column
one. This key does not cause an additional card to be fed
from the hopper.
38. Aux Dup (Auxiliary Duplicate): This key is operable
only when the machine hasthe auxiliary duplication feature
46
installed. Whenpressed, it causes duplication from the master
card on the auxiliary duplicating drum. Under program con-
trol, pressing the key once duplicates the entire field.
39. Prog Two (Program Two): With the machine underpro-
gram control, card format may be changed by operating the
program twokeyto place the operation under the control of
program two. Theshift between program level 1 and 2 can be
made any numberoftimes during the punching of a card.
When depressed in column | (auto feed switch off), this
key also causes a card feed cycle, and sets the corresponding
program level regardless of the setting of the program selec-
tion switch.
In a one-program application, if the secondlevel is not
punched in the program card, using the program 2 key sus-
pends programming. This makesit unnecessary to lift the
starwheels for program suspension.
44, Mult Pch (Multiple Punch): This key places the key-
board in numeric shift and suppresses spacing while individ-
ual codes are keyed and punched.
45. Prog One (Program One): This key causes the machine
program control to transfer immediately to program one,
assuming it had been in program two. (This key's function
is similar to that of Prog Two. See key 39.)
46. Error Reset: This key unlocksan interlocked keyboard.
The backspace key does not have to be used for this purpose.
Theerror reset key also resets an error condition encountered
during the use of the self-checking numberfeature. See
"*Self-Checking."
