$0  That's a zero.  Has always worked for me to produce a full path 
to a running perl script.

$ENV{PWD} is, as you say the working directory when perl, or the 
script as an executable with a shebang line

There is a module "cwd" I think which will keep $ENV{PWD} correct as 
you change directories around within a script..

As for portability to other than *NIX, I donno.
