    Default Do..Loop and Repeat..until

    Is there any reason to use Repeat...Until construction now we have the Do.. Loop / Loop While/ Loop Until?

    Not really John.

    Within the compiler, they both use the same condition parser code, but change characteristics to suite how the comparision takes place. i.e true instead of false, or vice-versa (Loop Until or Loop While). I added Do-Loop because, to me, it seems a bit more understandable.

    However this is not the case for While-Wend which will not even enter the loop if the condition is not met in the While statement, whereas both Do-Loop and Repeat-Until will always do the content of the loop first, which in some cases is not wanted.

    Thanks, that was what I expected, and I agree Do Loop is a much clearer syntax.

    That's exactly the difference between While-Wend and Repeat-Until. These two constructions should be sufficient and, what's more, compatible with other languages.
    Nobody ever suffered for thinking before doing
