Re^2: Use of uninitialized value

Erm . . . ouch.

The quotes around "$code[0]" are superfluous, to start
You could have just written it as "$code[0].$code[1].$code[2]" in one swell foop
Of course that locks you in to a fixed number of elements; if you want to join an arbitrary number of items in @code then just use join: $item = join( ".", @code );

If want a specific subset of elements, then you can use a slice: `my $item = join( ".", @code[0..2] ); my $not_item = join( ".", @code[9,7,0,3] );` [download] TGI says moo	[reply] [d/l]

Fletch, agreed that it's untidy as it is, but `$code[0].$code[1].$code[2] ne join( ".", @code )`. Best, andye Update: Anno is right, I did overlook a pair of quotes. Ignore me. :)	[reply] [d/l]

You overlooked a pair of quotes. Assuming that @code contains three elements, `"$code[0].$code[1].$code[2]"` is indeed the same as `join '.', @code`. Anno	[reply] [d/l] [select]

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]
