Notas y citas / Texto breve:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. From the invention of computer programming languages up to the mid-1980s, many if not most computer programmers created, edited and stored their programs on punched cards. The practice was nearly universal with IBM computers in the era. A punched card is a flexible write-once medium that encodes, most commonly, 80 characters of data. Groups or "decks" of cards form programs and collections of data. Users could create cards using a desk-sized keypunch with a typewriter-like keyboard. A typing error generally necessitated repunching an entire card. A single character typo could be corrected by duplicating the card up to the error column, typing the correct character and then duplicating the rest of the card. In some companies programmers wrote information on special forms called coding sheets, taking care to distinguish the digit zero from the letter O, the digit one from the letter I, 8's from Bs, 2's from Zs, and so on. These forms were then converted to cards by keypunch operators and, in some cases, checked by verifiers.
