Because I saw this in the printer example :-) And it kinda works.

It complaints about the (), i. e. it says ") too early". So I left the 
brackets away. Then it is accepted, but:

That's true, but the button is on the form, and so the form calls the 
procedure in the printing module. When I try what you say, this is what 
comes out:

in FMain Sub Button7_Click:

   druck.start

Too few arguments

   druck.start(drucker)

Unkown expression drucker

I tried all variations... no way to get it working.
