`my @x = chomp <DATA>;` Bingo, `@x` is gets a one-element list -- or at least, it's a list in list context and a scalar in scalar context. Tricky! Here's a mind-bender. What's this? `1, 2, 3` It could be a three-element list, in list context, or it could be a scalar and two void expressions (which get optimized away), in scalar context. In void context, it could be nothing. Update: Reworded one sentence.	[reply] [d/l] [select]

So, then, scalar also returns a list in list context? (BTW, `@x` is an array, not a one element list.)	[reply] [d/l]

when used with a list, it returns the total number of characters chomped... and not a list (so, you are right that there is no "list context" to it. []s, HTH, Massa (κς,πμ,πλ)	[reply]
