The Working Set is a CodeWarrior eclipse IDE feature, that allows you to group elements for display in views. With that, you can do operations on a set of elements in that working set. Especially when you are using many projects the same time, working sets are a big help to focus on the right set of things at a time.
To build/compile a Working Set:
The Select Working Set dialog box appears.
The New Working Set dialog box appears.
The C/C++ Working Set page appears.
The New Working Set dialog box closes and the newly created working set appears in the Select Working Set dialog box.
The IDE builds/compiles the projects included in the Working Set.
