I usually travel a lot, most of the time I would only cary my USB external storage. But I was wondering if there is any beter way, as currently I would save PERL folder with the script. So when I open it in another computer I would click the PERL script and then the computer would ask 'open with..' I would browse to the PERL folder and select the PERL interpreter. If there's way so that I just click PERL script and the computer know where to find the PERL interpreter? Thanks
