Thanks for clarifying the library and front/back script order - more 'LIFO-type' behaviour http://en.wikipedia.org/wiki/LIFO_(computing) than just random chunks of code in a bucket!
I think this thread has underpinned George Box's warning to “Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful.” Mapping this nascent MVC model has really helped me to force some recognisable structure onto LiveCode's flexibility, allowing me to map concepts from web-based technologies (HTML/CSS/Javascript/server API calls) onto LiveCode concepts and scriptable objects - and therefore decide how and where to put what logic for my Revlet-based web app. So, today, it's laying outside the 'very wrong/not very useful' model quadrant for me ... but which quadrant it will be in tomorrow? Who knows! :-) Best, Keith..
