Re^2: Can you create *real* global variables?

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.

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]
