[CWB] Impossible query

[Ruprecht von Waldenfels]

Hi,
well, there are a few topics concerning CWB on StackOverflow. The idea 
was to post here and there, so anybody who wants to answer can choose 
their forum (as you did).

Thanks for your answer! I was kind of suspecting there is some macro 
magic that can be used to accomplish this, but if it's scripts, it's 
scripts. Seems reasonable.

Best,
Ruprecht
