Afternoon all. I think, but I'm not 100% certain, that the source code for Turbo, The Editor etc, by the author who's name escapes me right now, are or were online many years ago. I may even have downloaded them at some point. I remember definitely looking through the source for The Editor so I did get it somewhere legal.
Having said that, I don't remember if Cport was included. Reverse engineering a compiled SuperBasic task might be more trouble than simply rewriting from scratch? If necessary there's a program I wrote yes ago, which Dilwyn updated, that decodes a QSAVE'd program. I'm certain that could be used as the basis for a new Cport lexer perhaps. It is called something like decode_qsave or similar. There's a doc file here, I think it's Word format: http://www.sitelevel.com/click?url=http%3a%2f%2fwww.dilwyn.me.uk%2fdocs%2fformats%2fsavfiles.doc&sid=YCsXx5g7rfbNG11e - which contains a listing of the program. Doing it as new should allow the cfix stuff to be included without needing a separate task to do it. Plus, it could be made easier to translate to C - how hard could it be? ;-) To be honest, I paid for Cport all those years ago, but have used it infrequently. It's a great idea, it fell down in practice. There always seemed to be far too much work post conversion just to get a clean C68 compile,never mind getting the code to work! Cheers, Norm.
