I'm curious to try to see how FreeBSD sh handles eval 'echo $LINENO', then. This will be a nice excuse to give it another try. > POSIX.1-2008 (aka SUSv4) says, at one point, that the shell shall "use > the delimiters as field terminators". [...] Ah! So something _was_ wrong -- the standard I was reading. That explains it all, thank you very much. When I have a more polished and complete LINENO implementation, I'll post it here.
