Talk:Break key
From Wikipedia, the free encyclopedia
[edit] Sinclair ZX81
The article claims that on the Sinclair ZX81, "the Break key is accessed by pressing Shift and Space." This is not quite accurate. When the computer is waiting for input (also in the INPUT statement), Space inserts a space and Shift+Space inserts a pound sign (£). When a BASIC program is running, both Space and Shift+Space act as Break. This has the consequence that a BASIC program imitating a typewriter with PRINT INKEY$ cannot be used to write a space. Reference: pages 60 and 128 (in chapters 9 and 19) of Sinclair ZX81 BASIC Programming by Steven Vickers, second edition 1981, printed at The Leagrave Press Limited, Luton & London. I'm not adding this to the article itself because I don't know how the ZX80 works in these respects. 82.128.240.144 08:33, 20 January 2007 (UTC)
