I may be missing the point you're making but HJO's statement referred to global variables. Other examples with variables explicitly declared as global: `$ perl -le 'local $foo = "whatever"; print $main::foo;' whatever` [download] `$ perl -le 'our $foo = "whatever"; print $main::foo;' whatever` [download] -- Ken	[reply] [d/l] [select]

Very true, but the OP also was using `my` variables in their original code. `our`, `local`, or undeclared (as you demonstrated) would work. --MidLifeXis	[reply] [d/l] [select]

All good - I see the connection: "it didn't work" was not referring to `$main::foo` (in the sentence preceding it) but rather `$main::log_name` (near the end of the post). -- Ken	[reply] [d/l] [select]
