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.

| Archimedes World Guide to RISCOS_CLI "VARIABLES" | Program : Example 6 | Purpose : Illustrates the use of Aliases | | N.B. vertical slash indicates a comment (like "REM" in BASIC) Echo Alias checking takes place prior to commands in the kernel. Echo DANGER! This means that the normal commands can be changed. Eg. Echo Echo Set Alias$Cat Echo Mieow! Echo *Cat Echo Set Alias$Cat Echo Mieow! Cat Echo Echo To ensure that the alias checking is skipped Echo preface the command by a percent sign % Eg. Echo *%cat Echo %Cat Unset Cat
