< Hi 
  Jens, 
 
I 
  looked at your code and the changes are done the right way. As already 
  suggested in my last mail, 
I would 
  try to convert postfix and prefix operation into corresponding methods. >
   
  I have done this 
  already
  the remaining 
  changes I have to do are:
  changing the UI 
  (adding labels and textfields for inc/dec) and implementing an if clause to 
  see whether I need the inc/dec methods
   
   < I think it makes the 
  
transformation easier since you don't have to 
  introduce temporary variables. >
   
  yes, I think so, 
  too
   
   < Another issue Adam 
  
brought up is: do we have to treat compound 
  assignments (e.g field+= 10) in a special way. May be 
you can spend some thoughts on that one 
  too.  > 
   
  no, 
  I think we could just use setField(getField() + 10)
  but 
  we should keep mind that Pre(Post)fixExpression is a subclass of 
  CompoundStatement
  but 
  we will have a problem with assignments within assignments but that's the same with
  "normal" assignments
 < I also added a SEF Test suite to 
  our test cases. So as soon as we make our test cases available 
  you 
have a starting point to 
  add your own test cases.  >
   
  sounds great
   I am a great fan of JUnit (great work, 
  Erich!)  and I am looking forward to use the test 
  suite
 < Do you still have the problems 
  with debugging. If so, what JDK are you using as a target VM ?  >
   
  I use JDK1.3.1 on Windows and 
  yes, it doesn't stop at breakpoints and the 
  hitcount
   seems to 
  be broken (it's always 0) 
 < I am looking forward seeing some 
  more contributions
