Last change on this file since 771 was 77, checked in by swagner, 17 years ago

Fixed ticket #67

  • adapted accessing of variables in operators due to changes of variable lookup and the new name aliasing mechanism (actual/formal name translations should not be done directly anymore; instead the new method Scope.TranslateName should be used)
