I'd vote for using /\t/ as it is much more self-documenting. Seeing `split "\t"` makes me wonder what `split '\t'` does. Well, all of these are the same (they split on tab): `split /\t/ split "\t" split '\t' split "\\t" split '\\t' split "\\\t"` [download] while all of these are the same (they split on backslash followed by "t"): `split /\\t/ split "\\\\t" split '\\\\t' split '\\\t'` [download] Did that surprise you? I can certainly seeing that surprising a non-perfect Perl coder who takes over maintanence of your code. I think `split $string` would be more DWIM if it translated into `split /\Q$string\E/`, which it doesn't. So I think you should avoid using it as it makes your code harder to maintain. (Except for the special case of `split " "`, of course.) - tye (but my friends call me "Tye")	[reply] [d/l] [select]
