It's really two strings: $string1 and $string2. Let me re-phrase my question a bit: I want to compare the two strings and I want to extract those chars that are matching each other in the first and second string (in order from the beginning), and put them in a new string (not array as I mistakenly said earlier). So, if I have $string1 = "C:\Program files\directory1\directory2\directory3" $string2 = "C:\Program files\directory1\dir2\dir3" then I want the output to be $string3 = "C:\Program files\directory1\"; > >my @string_array = split('', "onetwothree"); > > this would build an array with an element for each character.

It only gives me the number of how many characters that matches. > Good luck > > > > >What I want to do is, compare the arrays, one char at a time, from the > beginning and stop when I find two >chars that are different, putting the > matching chars in a new scalar. > > > >Any suggestions? > > > >Greatfull for any help! > > > >/Freddy > > > > > > -- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
