Thanks. I think this is what I will be going for.

I also found This thread, and was considering FindBin, but apparently FindBin is broken.

I'd still be interested in other options. If my script is invoked as ..\..\script.pl, won't that set $0 to ..\..\script.pl ?

Cheers,

$ echo '$0 & $0 &' > foo; chmod a+x foo; foo;
