Aha!

I thought it must be something like that - the issue that I was uncertain about what was what the neg-lookahead was applied to. It would seem it applies to the .{1,5} rather than the 'foo'.

Slightly non-intuitive IMHO, but I've got it now...

"Lookahead" implies "characters following", if it was "lookbehind" it would be "characters preceding". "negative lookahead" means that the following characters can not match. "Negative lookbehind" would mean that the preceding characters can not match. --- $world=~s/war/peace/g	[reply]
