Please put `<code>...</code>` tags around code. What's to solve? Are you asking why the package variables `$main::V1` and `$main::V2` aren't defined when `foo::fetchvar()` is called? That's because they were never set. Instead, you set the lexical variables (of file scope) `$V1` and `$V2`. Change the `my` declarations for `$V1` and `$V2` to `our` and your code will do what (I suppose) you expect it to do. Anno	[reply] [d/l] [select]

The "our" declaration is not documented in the second edition of Wall's book (1996). Oh, gosh, it is 10 years old... Time passes by. Thanks.	[reply]
