Punched cards, containing original data program levels, each program card can contain two in the form of punched holes, actuate the IBM machines totally different, complete 80-column programs. Either to perform automatically the various operations essen program can be selected for card to card use by setting tial to record-keeping. a program' selection switch. If it is desired to use both Original data is transcribed to punched cards by any program levels to control punching on a single card, of several types of IBM card punches. This manual ex alterations from program to program can be made by plains the operation of the most recent of these ma program selection keys on the keyboard. Programs can chines, the IBM 29 Card Punch (frontispiece). be alternated at will, while punching a single card, by means of these keys. Features Card Punching The IBM 29 Card Punch has the popular features of Eighty columns on the card can be punched. other IBM card punches, with additional features such Each column has 12 punching positions: one each as unlimited use of two program levels and pro for the digits 1 to 9, and one each for the zones 0, 11, grammed automatic insertion of zeros to the left of the and 12. The II-zone punch is sometimes referred to first significant digit in numeric fields, to provide as X. The digits are recorded by punching a single greater flexibility in the operation and application of hole in the corresponding digit or zero position of the the card punch. desired column. A letter is a combination of one zone punch and one digit punch in the desired column. For example, A is Programs a 12-zone and digit-I punches, N is an II-zone (X) The machine is easy to operate, quiet, and attractive. and digit-5 punches, and Z is a O-zone (zero) and One of its most important features is the simple means digit-9 punches. of setting it up quickly for automatic control of dupli A special character is one, two, or three holes in the cating operations, automatic insertion of left zeros, or desired column as shown in Figure l.
