help with substitution

[Erik Browaldh]

Hi everyone, thanks for the help last time!

if I have two strings
$word="cows";

and another given string:
$givenword="XXX-"; #with the same length as $word !!!

what I want to do is transform "XXX_" --> "cow-"

I have tried but cant figure out going characterwise, all I get in the end is like this:
$givenword="cowscowscows-"

thanks in advanced!

Erik
