I try to address them, I need some doc and code reading then. I'm new to your style guide. I hope the code in cvs is worth as example ;) [enterprise:~] andreast% cc -p hello hello.c consider using `-pg' instead of `-p' with gprof(1) .... Well it spits some errors, so I guess you're correct regarding the pic variant. Thanks again, Andreas
