Thanks I'll have a look at Algorithm::Diff.
Also, I found the BasicPerl Function Tie I never saw, I ain't sure (havn't read exactly what it does yet) but in the Sample Codes it looks usefull.
Thanks anyway, Ill have a look into these things. Ill rewrite this. And by the end of the day if I couldn't find a way to fix this I'll have to breakout the nasty qx!!; to execute an external command.

Thanks!
