In regards to the comments and 'declare now, use later' I'm still working out what makes code have clarity and what is unneeded. (I've also just understood what my is used for, apart from being able to stop strict from complaining, so I might do less of that 'declare now, use later' stuff from now on. :) )

I'm glad you used Getopt::Long as that is something I've wanted to use in this script. You've given me a good head-start. :)

Thanks
