Sorry, there are a few things that I don't understand... and I am not so
good in mathematics... and I can't explain it in English quite well. 

The same seed generates the same random sequence... or not?
and why I can randomize as often as I want in the same program?
A loop like this generates the same numbers:
for loop := 1 to 100 do begin
  writeln (random (1000) +1);
How can I re-seed in the same program?


(Please, use the list if you can answer, otherwise I won't receive it)
