Perl "require" question

stevensw has asked for the wisdom of the Perl Monks concerning the following question:

So a script can tell where it's located by the $0 variable right? OK

So what if another script calls "require" on it? Does calling $0 still refer to where it's located? Apparently not, it refers to the script that called require on it. So when that required script tries to call require on other scripts using relative paths, those requires fail if the requiring script is not found in the same directory.

Is there a way to fix this? Thanks

Both `$0` and `$FindBin::Bin` in a required module still point to the main programme. `__FILE__`, on the other hand, does not. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l] [select]
