I checked and it also works on my home PC. (perl v5.6.0 on Win32)

Only thing I can think of is: the code should all be on one line (if you cut and paste from above it will include some newlines and '+' characters: I tried that and it gave no output.)

If that's the case try clicking d/l code to download the code instead. (and if that doesn't work let me know!)

Cheerio!
