This a an example of dirty programming!

From the viewpoint of a computer scientist (I'm one) this is a not a
syntactically correct defiend for-loop. The variable of a for-loop
belongs to the for-command and should be never _changable_ by the user. 

Sorry for flaming, but this are the programming styles, which make
software packages difficult to maintain, debug, readable and
understandable by other programmers.
