i strongly recommend the following books if u want to get serious about OOP

1) Essential Actionscript 2.0 - http://www.amazon.com/Essential-ActionScript-2-0-Colin-Moock/dp/0596006527/sr=1-4/qid=1161183848/ref=sr_1_4/102-9410879-8010537?ie=UTF8&s=books
 
2) Head first design patterns - this book is written for Java but the same OO concepts can be used in flash (must buy) - http://www.amazon.com/Head-First-Design-Patterns/dp/0596007124/sr=8-1/qid=1161181139/ref=pd_bbs_sr_1/102-9410879-8010537?ie=UTF8

Thanks a lot, Mike

used "public static function String2Date"
and "CommonFunctions.String2Date(...)"

I'm a search-trialanderror-and-search-again type of programmer. Just
learning as I need something :-)

Any suggestions on good OO-related basic learning sites ?
