- There's at least 30 lines in the documentation that was installed on your computer, see C:\Perl\html\index.html under 'PerlScript' and 'PerlScript examples'. Documentation is limited I fear.
- I tried an example with use Data::Dumper; which worked well. I suppose @INC might be limited to the ActiveState directory though.
I've no answer to your other questions though.
