Nope, try it another way: my $str = "$this and @that"; # -> Use of uninitialized value in concatenation (.) at .. bla bla There may indeed be concatenation going on in building the string, but my question is more to do with whether I'm the only one who thinks the message is a bit misleading with the 'concatenation (.)' bit. I can't see a single period in the string: "$this and @that" and I'm not explicitly joining anything. Woof Ciao Richard Foley --- richard@rfi.net 'Ciao' - shorter than 'Aufwiedersehen'
