Notepad++ 内置了一個稱為 UDL2.0 (User Defined Language) 的引擎，來實作使用者自定義文法高亮，使用它，可以定制自己的代碼語言。
相關的參考：

ABB Rapid 文法類似于 Pascal，Ultraedit 文本編輯器已經有文法高亮定義。是以，可以在參考并引用其中的關鍵字等資訊。
Ultraedit 的語言定義檔案：http://www.ultraedit.com/files/wf/abb-s4.uew
之是以要使用 Notepad++ 而不是使用現成的 Ultraedit 是因為後者是收費軟體，完全可以用前者來代替。

圖：在 Notepad++ 中自定義語言
文法高亮效果：
添加了 regin/endregin 注釋折疊
另外，追加了幾條 Arc 指令。
