What is the syntax for a nested for-DO LOOP statement in Pascal?

What happens when a conditional expression is false in a loop?
Notice that the conditional expression appears at the end of the loop, so the statement (s) in the loop execute once before the condition is tested. If the condition is false, the flow of control jumps back up to repeat, and the statement (s) in the loop execute again. This process repeats until the given condition becomes true.
