I'm trying to put together a brief timeline of the evolution of the 4GL/ABL for a co-worker who is coming from outside the Progress community; in particular with respect to the evolution of code and object re-use / persistence. One thing I can't remember though is when persistent procedures were first introduced - was that with v7 or v8? I'm leaning towards v8 (since they are heavily used in ADM1), but I may be wrong. But then I know a bunch of features like internal procedures, UDFs, handles, dynamic widgets etc. were introduced with v7. I'm pretty sure SUPER procedures didn't arrive until v9. I can only get online/electronic documentation as far back as 9.1D, and we no longer have any physical v8 manuals around here. As far as I'm aware we were never on v7 or earlier so wouldn't have those anyway.
