Is this loop construct only available using goto's???

I know the answer must be NO!!!, but I can't think of a direct way of doing this.

Code:

BEGIN LOOP
loop statements;
.
.
.
TEST(test_condition)
update statements;
.
.
.
END LOOP

I hope that was clear. The main features I am trying to create are these: the loop iterates once before testing anything. Then it tests the condition BEFORE running the update code. Lastly, the update code contains multiple statements. It seems to me the none of for, while and dowhile loops really want to do this, although it would be possible. Implementing with goto's is really, really easy, but I was told to never ever use them.

Thanks a bunch.

erm, what's wrong with while loop?

Code:

while(1) {
   loop statements;
.
.
.
TEST(test_condition)
update statements;
.
.
.
}

Thank you!! I knew I was being thick! I was just stuck with the idea that the test part of the standard loop structure had to actually be the test.

Thanks again.
