var watcher behaviour

[Jochen Stenzel]

Hello,

here comes another script. It installs a number of var watchers and then
modifies the variables. As you can see in comments, this was intended to
become another grouping test script, but the error has to do with var
watchers: whenever I modify a certain variable, the associated watcher is
called MULTIPLY.

Greetings

                    Jochen
