I thought different. To me a "command line" is something that's entered at a prompt, and whilst makefiles contain commands, I've never thought of them as containing "command lines". But thinking about the numbers involved (ie 8192), I'm starting to think that your interpretation might be more to the point than mine :-) Cheers, Rob
