No, it can be anything, and the actual value even depends on the

I would NEVER rely on this in production code. The value of the control
variable of a For loop after execution should never be relied upon. A simple
change in the compiler at some future point could break a lot of your code.
To be honest I would call it a bug if a comipler didn't warn about it

No. I think it is even specified in the pascal standard.
