[Cuis-dev] [QUESTION] how to move changes to a pre-existing class's definition into my own pkg

[Juan Vuletich]

Hi Imran,

Welcome to the Cuis community!

In Cuis, a package can not modify the definition of existing classes, or 
their class comment. For existing classes, these need to go in numbered 
ChangeSets.

If you have already exited your image without saving it, chances are 
these changes are "lost". But you can recover them from the appropriate 
*.user.???.changes file.

Hope this helps.

Cheers,
