Summary
[edit]Description | Example of a statement in the Klerer-May programming system.
From Figure 5 of M. Klerer and J. May, *A user oriented programming language*, The Computer Journal (1965) 8 (2): 103-109. doi: 10.1093/comjnl/8.2.103 |

Use in article (WP:NFCC#7) | Klerer-May System |
Purpose of use in article (WP:NFCC#8) | The most notable feature of the Klerer-May System is its two-dimensional notation, so an example of that notation is crucial to understanding the work. |
Not replaceable with free media because (WP:NFCC#1) |
n.a. |
Not replaceable with textual coverage because (WP:NFCC#1) |
The Klerer-May System used a custom modified teletypewriter (Friden Flexowriter), and the exact typography of this system is of historical interest, and this would not be captured either by text or a newly created image.
Wiki text is not capable of producing even a good approximation of an illustrative example of a Klerer-May expression. |
Minimal use (WP:NFCC#3) | One example of several from the source paper is used. The example shows a single programming language statement, which is the smallest unit appropriate to illustrate programming language statements. |
Respect for commercial opportunities (WP:NFCC#2) |
The full paper from which the example is excerpted is available without charge from the publisher at
http://comjnl.oxfordjournals.org/content/8/2/103.abstract so the selection is highly unlikely to harm any commercial interest of the publisher. |
Other information | The image is classed as a ‘software screenshot’ as the closest available category, although the device was a teletype rather than a screen. |
