is it possible to do this same thing with different domains?
For example if x=1 and List=[1,2,3] in your example? What is the comparator to be used?

Thank you for the example.
There is some stuff here I don't understand but I'll work through it using debug to learn.
Again, thanks for your reply.

Folks, could anyone provide an example of how to use "removeAllBy". There is no such example in the programs provided under examples and I don't understand the arguments that need to be included.

Thanks in advance

I understand that I can introduce a "addNativeMessageHandler(onNative)" and then detect and act on key presses that way...such as this code to detect a keydown and keyup events for the left shift key: implement keyDown inherits formWindow open core, vpiDomains clauses display(Parent) = For...

I cant seem to capture a "onKeyDown" event. I contstruct a simle form called "keyDown", that has both a "setKeyDownResponder" and a "setCharResponder" implement keyDown inherits formWindow open core, vpiDomains clauses display(Parent) = Form :- Form = new(Pare...

Perfect, thanks!
