Hi again Great thanks to all the quickly answers! I tried a couple of them and - yes it works - thanks!
But how does it work? "if(string =~/^[0-9]/)" The part string =~/^[0-9]/ - does it split the string into single numbers and check if each of them is a part of the list [0-9] ?? I want to be scour that I have understood the Principe correct.
