Questions from a new member

[Pascal]

Good morning.
I received a few questions from a new subscriber.
As most of you know it, I always prefer to publicly respond to general questions sent to me privately.
Today - and for the whole week - however I have big time constraints which prevent me to post much.

I understand that Billy could easily respond, but I was thinking that maybe other members could respond too, or at least at this point, I'd expect that most members would know the answers to these questions.
Therefore, I will leave it to you to answer.

I would like to take this opportunity to welcome about ten new members who joined our Robot followers group last week.
Do not hesitate to ask questions, even questions that you feel might have been answered already.
It is better to ask questions and get answers than not asking them and then dropping out because you do not understand how the Robots work.
