To the OP, don't get hung up on the syntax we use to implement a loop.
I took my first programming class long enough ago that we had to do
things like this (roughly translating the FORTRAN IV I remember into
p-code)
To do:
while TrueCondition
(loop body)
we'd have to write:
TopOfLoop:
if not TrueConditional goto loopEnd
(loop body)
goto TopOfLoop
loopEnd:
We were even required to write our source twice:
The first pass was "structured" and had to be proven correct.
The second pass was translated into something our compiler supported.
We still called it a "while loop" even though the syntax was icky.
When C came out with its built in looping, it was an unbelievable
luxury.
