The doted underline (\uld) doesn't have parameter that's why RTF control ignores whatever you're entering. You may consider some other RTF control word, maybe annotation, for that purpouse.

>the attached parameter is one which i assign myself when creating the asci/rtf file. i must have a unique meaningfull id when user clicks on a specific word. i then check to see if this word is underlined and what the id is, and then performe certain task depending on the id i found 'attached' to that word.
