I have a string and want to alter all the instances of a certain character within in it. Here is my feeble attempt:
$instring = "This-is-my-string";
$outstring = "";

for ($i=0; $i   length $instring; $i++)
{
  if ($instring[$i] ne "-")
  {
    $outstring .= $instring[$i];
  }

  else 
  {
    # replace with a new character or substring
    $outstring .= "_"; 
  }
}

print "$outstring";

The desired out put would be "This_is_my_string"
