vim indentation

<p>I'm using vim to edit files that use a programming language where the end of line is not marked with ;. This causes problems when I try to fix indentation in vim. If I put a ; at the end then vim is able to correctly fix the indentation, but since this programming language doesn't have a ; at the end of a statement the indentation isn't correct after vim tries to fix it. How can vim be modified so that it works correctly with this programming language?</p>
