!BasicProg/!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.

Back to Basics: Learning to Program in Basic By David Matthewman In the last part of the Back to Basics series, we look at indirection operators, used to read from and write to memory directly form Basic. In order to run Listing1 in the BasicProg directory, you will need to copy the three files in the directory to another disc and then run the SetVar program. For more information, see page 91 in the magazine. � Copyright Acorn User 1994
