Nigel, The Compiler changed some versions back and no longer detects all error sin one pass...at least in certain situations. A few tips and things to look out for:
* If you've got a missing method, the Compiler usually stops reporting errors, even if there are multiple cases of the problem. * Sometimes, code doesn't seem to be scanned. I use a method to retokenize all methods (pasted below) which helps. Note that you get an error on this most of the time when the method tries to retokenize itself. * If you compile with 'all variables are typed ' (and you are likely to find more genuine errors this way), then periodically do a syntax check with 'type the variables.' If you've got inconsistent declarations, this can turn them up. There are still a number of things that the compiler won't do - even in V16: * Check parameter list lengths and detect extra params in some cases. * Check parameter list lengths and detect missing params in any case. (There's no syntax to declare a method parameter as optional in 4D.) * Check method name references, like with New process, ON ERR CALL, etc. There's also still no way to declare that a parameter is a method reference. I've already got a feature request in at forums.4d.fr for these improvements. If you like these ideas, or have related suggestions, please comment and vote here: Compiler/Typing Improvements: Detect some runtime errors in advance http://forums.4d.fr/Post/EN/19107688/1/19107689 I have to say, I've got zero evidence to make be believe that the forum voting makes any difference at all...but I'm new over there. So, maybe I does. I do know that 4D officially ignores comments on this list, so everything here is just chat. If, like many of us, you don't guess how to vote properly, here's a Tech Tip that Tim Penner kindly pointed out not too long ago: Tech Tip: How to vote for a feature request http://kb.4d.com/assetid=76726 Here's that method I promised earlier.
