!ArmCode/!Help
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.

Assembly Line By Dave Lawrence Run this application to open a Filer window containing five Basic programs. Basic1 uses recursion to display a 'Persian carpet', and Arm1 is an assembly language version of the program. Basic2 again uses recursion, but this time the program sorts a set of integers into increasing order using the quicksort algorithm. Arm2 is an assembly language version of quicksort. Debug is an assembly macro which can be appended to your Basic source programs. It provides a function called FNdebug which can be called from assembly language to display the values of Arm registers at any time. Full details are provided in the magazine. � BBC Acorn User 1993
