The I have used and liked are: SlickEdit which does cost quite abit but will work as complete C/C++/java development enviroment. It has highlighting for Perl and other languages as well, and a powerful macro language to boot. ConText is a simpler but free text editor with highlighting. Good and simple. Eclipse with the EPIC Plugin is the best total environment for Perl I have seen in this kind of tool (But I don't get out). Oh,Free as well UltraEdit is also very good.
