That's all it takes. Indeed I just wanted the default but I didn't knowI could just unset the variable. Sounds like the sort of thing thatmight cause some sort of deep breakage like erasing your $PATH orsomething. Anyway the unset seems fine, thanks Bart and Vin. Probablyif I was better I could avoid tinkering with IFS at all.
