Did I? Surely if `@code = qw(foo bar baz)` then `$code[0].$code[1].$code[2] eq "foobarbaz"` whereas `(join '.', @code) eq "foo.bar.baz"` ? All the best, andye Update: You're completely right, I overlooked a pair of quotes. :)	[reply] [d/l] [select]

Update: You're completely right, I overlooked a pair of quotes. :) That is because the OP's code was so messy to begin with: one more reason to write it in a saner, more terse way!	[reply]
