Thanks to Marian Meinhard, Notepad++ users can finally use INPs without hurting their eyes:
1. Go to:
2. Download the Abaqus xml file (userDefineLang.xml) and save it in your Notepad++ directory.
3. Start Notepad++ => "View" => "User Defined Dialogue.." Import the downloaded file (userDefineLang.xml). In the "User Language" drop-down menu, you should now see Abaqus, which you are free to edit.
