I some languages the do...until syntax always executes at least once because the test it as the end. This applies equally to the do...while syntax that some languages have. The other issue is why use the word "while" which implies some sort of "negative" condition because the loop operates until the condition is false. But equally it can be seen as a positive condition -- the loop operates provided it is true. One thing is for sure -- it is not fashionable these days to provide both 'while' and 'until' loops these days since most programmers are happy with either form. > For none programmers i can say that probably 99,999 would express the > later as more clearly expressed, so why do programmers prefer the > former "negated statement", is it an occupational injury of the > programming environment? It's natural for you. For other people looping when something is true is more natural. For others (like me) neither is natural. People who hold this sort of string opinion about "natural" constructs often end up writing their own programming language that does everything in the "obvious" and "natural" way, only to find out that no one else wants to use it. <snip> -- Ben.
