I am looking for files from the directory below that once found a home on ftp.cdrom.com, but so far searching the various compilation CDROMs (like Walnut etc) has drawn a blank. http://mirrorservice.org/sites/ftp.cdrom.com/pub/cdrom/cdroms/math/global.t… If anyone has the ISETL*.ZIP files [*] from the directory cdroms/math/msdos/discrete/ or even the whole directory, I would be interested to receive a copy please. If you have a mirror of that site it would be good to get it copied to mirrorservice.org so we have a public copy too. thanks, nigel. [*] I found the ISETL.ZIP file but would like the source-code too. ISETL is an implementation (interactive interpreter) for the SETL programming language.
