My guess is that a greater percentage of people using OOP in 1991 had a better understanding of it than those 1993. It doesn't mean OOP is a failure, just that you have more people in 1993 entering OOP and you have the training curve to deal with. Unfortunately they jumped into the OOP pool without first learning how to swim. They may have taken a lesson or two and could hold their own in calm waters, but when things get rough they drown. In stead of realizing they lack knowledge and accepting the responsibility for their failure they point the finger at OOP. -------------------------------------------- David Bradley davidb@datalytics.com Software Engineer Datalytics, Inc. http://www.datalytics.com
