Message removal question

I know this is going to sound noob but unfortnatelyI have not found a GUI way to do what I want to do.

I want to add a command that removes any text messages on the screen however I cannot find anything stating that it can be done.

am I overlooking something or does this have to be done through JASS

rofl

well thats where it is then
they should put it with the game display stuff. lol

thank you
