We may be all, ' semicolon ' in front of it, and fill the ' comma ' or ' semicolon ' may be just ahead, but behind the comma may be with or without '. ', or ' comma ' is to be used only for the forward.
Forward we might fill the 'semicolon' ahead of it and fill 'comma' back. Or just fill 'semicolon' forward. But behind either with or without 'comma', or take a 'comma' forward alone time.
In front of us may fill the entire 'semicolon' in front of it and add the 'comma' back. Or it may be filled only 'semicolon' forward. But behind may or may not have 'comma' or 'comma' forward alone.
