Code Syntax Highlighting in Delphi 6 (to highlight syntax and ifdef blocks)

Delphi 6 is pretty old, I know. Unfortunately there are reasons why I can't upgrade which I don't want to get into here.

My problem is that it's hard to read code. I have the Castalia plugin which helps a bit (parenthesis matching, shows blocks of if, e开发者_如何学Clse, end) but it doesn't highlight the syntax like other IDEs do (variables, constants, procedures, etc.) in different colors. It also doesn't show the IFDEF blocks which can be very confusing at times.

For Delphi 6 what plugins can do some or all of these features?

CnPack will work on Delphi6, and it highlights {$whatever} symbols. http://www.cnpack.org/index.php?lang=en
