explained in detail in a paper in the Computer Journal. Input The fast computing speed of Atlas and the use of multiple input and output peripheral equipments enable the computer to handle a large quantity and variety of problems . These will range from small jobs for which there is no data outside the program itself, to large jobs requiring several batches of data, possibly arriving on different media. Other input items may consist of amendments to programs, or requests to execute programs
developed and special S.E.R. 's have been written to control them. When demands on storage exceed the capacity of the main store and input and output tapes, a separate magnetic tape, the system dump tape, is used to hold information not required immediately. This tape may be called into use for a variety of reasons. Execution of a problem may be suspended and the problem recorded temporarily on the dump tape if other problems are required to fill the output well, or alternatively if its own

called a tape v . A switch of functions between the two input tapes occurs when a tape v is exhausted. The tape u is then rewound and becomes a tape v, and t ape v likewise is rewound and becomes a tape u. To avoid holding up calculation while tape u rewinds, a special control card can be inserted anywhere in the input pack which causes it to rewind and wait, so that reading can start as soon as the switch takes place. At the beginning of a work session, there is of course no tape v. Reading
