General Description
This instruction enables the Card Punch Model 334 to punch 80-column cards from information contained in
the HSM, using the Simultaneous Mode.
Format
Operation — 3
N — Must be zero (0).
A Address — HSM address of first character to be punched.
B Address — HSM address of last character to be punched.
Direction of Operation

Outline of Operation
Initially this instruction is staticized in the Normal Mode. If the Simultaneous Mode is free and the SMDI
Dutton is not on, the contents of the NOR Register are transferred to SOR Register, and the contents of the A and
B Registers are transferred to the S and T Registers respectively, and this instruction is executed in the Simultaneous
Mode. The operation of the instruction is as follows:
A start signal is sent to the Card Punch. Punching by the Card Punch is initiated and continues until all the
characters between and including the HSM locations specified by the S and T Registers are punched. When the
contents of the S and T Registers are equal, the last card is punched and the contents of the S Register are incre­
mented by one. The card punched is read concurrently with the punching of the succeeding card to insure the
accuracy of the punching.
Final Register Contents
(S) = HSM address of location one to the right of the last character in HSM punched.
f
(X) = (B),
r

Cards are punched at the rate of 100 cards per minute.
