I'm not certain how you have it coded; indentation tends
to be strange in a newsgroup posting.

If the print and assignment are indented, I would expect
it to print all three integers, one after the other.

If they are not indented, then I would expect the behavior
you got: the for loop executed to completion with a
null body, and then the print statement executed
with the final value of "i".
