in thread Can I from within a module access variables from the calling program?

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
$ perl -le 'our $foo = "whatever"; print $main::foo;' whatever

    Very true, but the OP also was using my variables in their original code. our, local, or undeclared (as you demonstrated) would work.

      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).
