At the time the language was formally defined it was typical for code to be stored on decks of [[wp:Punched card|punched cards]] (or [[wp:Punched tape|paper tape]]). Possibly because storing code on [[wp:Hard disk drive|disk]] (or [[wp:Drum memory|drum]]) was expensive. Similarly |
At the time the language was formally defined it was typical for code to be stored on decks of [[wp:Punched card|punched cards]] (or [[wp:Punched tape|paper tape]]). Possibly because storing code on [[wp:Hard disk drive|disk]] (or [[wp:Drum memory|drum]]) was expensive. Similarly card decks can be read sequentially from ''just'' one [[wp:Punched card input/output|card reader]]. It appears the Algol68 "standard" assumed all cards could be simply stacked before and after the actual ''source code'', hence the references "prelude" and "postlude" in the formal standard. |
