While Mike has pointed you to the right reading material, one might briefly say that the class concept in ABL is basically the same as the class concept in any OO language. As with any language, there are features which may or may not exist and one needs to be in tune with that. Since OO is still relatively new to ABL, one might expect there to be a few more "missing" bits, but PSC has been doing pretty good at adding new features with each release so many of the shortcomings of the initial release are now taken care of. Also, one needs to be sensitive to the fact that ABL is a 4GL, unlike the popular OO languages, so there are times when the best implementation in ABL is going to differ in some ways to what you might be used to in a 3GL OO language.
