Gang punch
Punching the same data into an entire deck in one pass — the punched-card era's version of a column default.
The date, the account number, the department and the cost centre were identical on every card in a run, and having a keypunch operator type them card by card was both expensive and a reliable source of errors. Instead you put a master card at the front of the deck and let a reproducing punch — an IBM 513, 514 or later 519 — copy the constant fields into every following card until the next master card came along. The operator at the keypunch only keyed what actually varied.
The effect was practical and slightly unnerving: a deck carried its own context, so a card that strayed into the wrong deck brought the wrong date into the next run and nothing on the card gave it away. The word survived as a verb — to gang-punch something — long after the cards were gone, and the operation itself is unchanged in every UPDATE that sets the same value on ten thousand rows.
