This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

Back to Basics: Learning to Program in Basic By Mark Moxon Run this option to open a directory containing three example Basic programs from the third part of the series on learning to program in Basic. Listing1 implements a very simple arithmetic quiz. Listing2 uses a WHILE-ENDWHILE construct to provide password protection: the password is AU. Listing3 uses a REPEAT-UNTIL construct to provide a 'three attempts' password system: again, the password is AU. For more information, see the article on page 101 in the magazine. � Copyright Acorn User 1993
