I like jr's suggestion.

The way I do it is with parsing.  You can't really control the noise 
around you, so make your noise noticeable.
i.e.
#debug concat("[myData] ObjectWidth ", str(ObjectWidth,0,3), "\n")

Then you know any line beginning with [myData] is one you care about for 
this application and you can ignore everything else.
