    Hello,

    I have found a couple of ways of replacing text within an array, but can't get either of them to work. This would point to human error, but I can't see where I'm going wrong:

    (1)

    @config = map {s/oldtext/newtext/g; $_; } @config;

    for $t (0 .. $#config)
    {
    print"$config[$t][0]\n";
    }


    This doesn't produce the expected results though, as the oldtext remains and has not been changed at all.

    (2)
    The 2nd approach I have tried is:

    for (@config) {s/oldtext/newtext/g}

    and when I print this out using the same bit of code as above, this doesn't work either.


    So can somebody please tell me how I can replace text within an array (each element is a line of text)???

    thanks!
