If your actions inspire others to dream more, learn more, do more and become more, you are a leader.-John Q. Adams You must accept one of two basic premises: Either we are alone in the universe, or we are not alone in the universe. And either way, the implications are staggering.-Wernher von Braun Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.-Albert Einstein
Suppose we run two programs on a single-core processor
First sets the EIP pointer to 2 (example)and the second one sets it to 1
How does the first program know it will continue from adress 2 and not 1 ?
Thank you very much

Each program runs in its own address and activity space, totally isolated from the other. As one is pre-empted, its environment, including registers, is saved and then restored when it gets its next timeslice.

Sorry to correct you - albeit slightly - but I was referring to the initial entry of Barrett. In a later interview, Richard Wright said:
"One thing that really stands out in my mind, that I’ll never forget; I was going in to the the Shine On sessions. I went in the studio and I saw this guy sitting at the back of the studio, he was only as far away as you are from me. And I didn’t recognise him. I said, ‘Who’s that guy behind you?’ ‘That’s Syd.’ And I just cracked up, I couldn’t believe it… he had shaven all his hair off… I mean, his eyebrows, everything… he was jumping up and down brushing his teeth, it was awful. And, uh, I was in, I mean Roger was in tears, I think I was; we were both in tears. It was very shocking… seven years of no contact and then to walk in while we’re actually doing that particular track. I don’t know – coincidence, karma, fate, who knows? But it was very, very, very powerful.”
