No, he means to go back to the top of the loop for the next iteration.
Here's a silly example:
for i = 1 to 10
if remainder(i,3) = 0 then
resume
end if
printf(1, "%d is divisible by 3!\n", i)
end for
So you should see:
3
6
9
I typically use a big if statement to do that sort of thing (of course this
is really trivial):
for i = 1 to 10
if remainder(i,3) != 0 then
printf(1, "%d is divisible by 3!\n", i)
end if
end for
I suspect that this shouldn't be terribly difficult to do in the source. I
*think* I see an easy way to do it by basically adding a case (or two). The
only thing that would slow me down would be adding stuff into the parser,
which I haven't done yet--a lot of that stuff is still a black box to me. :)
The controlled exit looks like it would take some more work--mainly checking
to see how many/which loops you need to wrap up.

The 'exit' instruction itself is a plain and simple goto.
The same would be true of 'continue' or 'exit(n)'. The only difference
is the compile-time determination of where to jump to.
When the compiler handles 'end ...' it resolves a list of outstanding
'exits'. It would not be difficult to associate a decrementing count
with each exit, which could post pone the resolution
