Thanks for the pointer. I added that "| ... |" just for documentation. You are right, it impedes experimentation in the workspace.

Hi Marcel
It works fine.

Note that if you do not define
- model
- view
as block variables | model view |
and thus have them as workspace bound variables you may execute single
statements later on the same morph and thus see the effect of the
statement dynamically applied.

Kind regards
Hannes
