They're probably using the terminology of Wegner's OOPSLA paper ('86 I believe but I'm not sure) "Dimensions of Object-??? Languge Design." A good paper to make sense out of all the object oriented mumbo jumbo. -- Jorge A. Gautier| "The enemy is at the gate.

I've heard said that Ada is "Object-based" as opposed to "Object-Oriented". Now I make no pretentions about knowing some undeniable truth as to what "Object-Oriented" means (this being the subject of many a discussion at OOPSLA), but could someone enlighten me on what "Object-based" is suppose to mean?

My understanding of "Object-based" is that it is a system using objects but without inheritence. Object based systems allow you to create objects (at run time) and have methods that apply to that object but the methods can not be used for other objects as can be done with inheritence. Not being familiar with Ada I don't know if it is object based. On a project I am currently on is Object based due to some constraints which due not allow us to use inheritence. I have found it to be a useful approach and more powerful than C which is what the object based system is built on. =============================================================================== Mark Kornfein INET: kornfein@crd.ge.com GE Corporate R&D Center UUCP: uunet!crd.ge.com!kornfein Schenectady, NY
