in reply to Replace the nth occurence

The built-in substr function does it:

my $count = 3; my $str = "a,b,c,d"; substr $str, $count, 1, '|'; print $str;

    Have you tried to replace the 2nd comma in the following string using your code? Seems there is room for improvement...
    my $str = "aa,bb,cc,dd";
      It doesn't even work on the example string for any count other than three--it was just a coincidence that it happened to be in the right position in that case.
