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.

set <variable> <value> [<variable> <value> ... ] assigns a value to a script variable. <value> should be quoted if it includes spaces. More than one variable/value pair may be set at once. Some variables are defined automatically during script execution. These are: $status contains values returned from script commands, often indicating success or failure, but can indicate more detailed results. port contains driver and port in use (set by "port" command) speed contains baud rate (set by "speed" command) ipaddress contains IP address detected by "ipget" command. Setting this variable causes automatic recalculation of the variables ip1,ip2,ip3,ip4, and updates the "IP" address field in the status window. ip1,ip2,ip3,ip4 contain the four components of a detected IP address. route set to %ip1.%ip2.%ip3.254 by "ipget", but you can of course alter it yourself. p1 p2 p3 (etc) parameters passed to a subroutine. Note these are NOT preserved throughout the execution of the subroutine and will be destroyed by further calls to other routines. Transfer values to variables of your own if you want to keep them for later use.
