A do-file location: how the code inside that do-file find it?

Hi!

Let's say script A call a subscript B either by do, require, or
use. Now the code inside subscript B need to know what the file
location of subscript B. How this can be done?

The perldoc page of do mentioned that perl will keep track the
file name (e.g. for error reporting), how to get access to this
file name recorded by perl?

Thanks!
