I had the original SuperBASIC Production Kit from Sinclair at the time, and you are correct that the important bits were in files with filenames consisting of spaces and underscores. Somewhere (and I emphasise _somewhere_ as I have had builders in here for several weeks now!) I still have the original SPK from Sinclair. At the time it was strictly licenced and intended to help early software producers produce software quickly and easily by introducing copy protection, faster loading of basic programs and BREAK disable. -- Dilwyn Jones [EMAIL PROTECTED] http://www.soft.net.uk/dj/index.html
