Program printout
A program listing ( English listing ) is a printed list of computer commands , usually in the form of a computer program or computer data . It is printed in a human-readable form (usually rows of numbers and letters).
In the 1980s in particular, computer game magazines and books often had program listings to type in, mostly in BASIC or assembler , sometimes for several home computer systems. The first successful such book was in 1978 Basic Computer Games (in German BASIC computer games ), published by David H. Ahl ( Creative Computing ). In Germany the books were published in 1982 by Sybex- Verlag.
Many magazines, including the 64's, used input aids, such as special editors (MSE) or checksums, to make troubleshooting easier with checksums . In some systems, such as the Commodore 64 , graphic and control characters often made input difficult. Therefore, these have often been replaced by plain text . For example (DOWN5) for 5 × Cursor Down or (SA) for Shift + Key A. Alternatively, the conversion was also carried out using software such as Simons' Basic .
In the past, a program expression was mainly used for error correction . Printing on continuous paper was common . This type of use has decreased due to the better options for screen display. Today, program printouts are mainly used for training purposes or to publish a specific issue.
