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 the example Basic program from the seventh part of the series on learning to program in Basic. Listing1 provides a very simple word processor. Run the program and the screen will clear. At the bottom of the screen is a dashed line: below this is the editing areas. Above the line is the actual document. Use the keys A and Z to move the star up and down the left-hand side: this star is the cursor showing the current line. At any time, press E to enter edit mode. A question mark will appear at the bottom of the screen, and you can type in any text you want, up to a maximum of 75 characters. When you press RETURN, this text appears on screen. If you want to right-justify some text, simply position the cursor on that line, and press R; if you want to centre a line, position the cursor and press C; finally, to left-justify a line, press L. For more information, see the article on page 105 in the magazine. � Copyright Acorn User 1994
