in reply to How to insert a "/" within a string?

index + substr:
my $str = 'ABCOPCOGNHVCOHL'; my $index = 0; while (($index = index($str, 'CO', $index)) > -1) { substr $str, $index, 2, 'C/O'; } print "$str\n"; __END__ ABC/OPC/OGNHVC/OHL

    To be in the same spirit as most of the other solutions proposed here, you should have written ($index = index($str, 'CO', $index)) > -1 as

    lc($index = index($str, 'CO', $index)) =~ /^-/

    Or using substr to insert a string between two characters:

    $_ = 0; substr $str, $_ + 1, 0, '/' while ($_ = index $str, 'CO', $_) > -1;
    True laziness is hard work
