Nope, they were just written in C. It was object oriented C, but without a C++ compiler. Do you know the story about the whole C++ toolset that was rolled out by R&D and promptly rejected by production? That happened before my time, but according to legend is what lead to PDI’s strict avoidance of C++… until a couple of years into the DWA merger. (Clearly there were some problems beyond C vs C++, but I don’t know the whole story.) Anyway, yeah I remember starting on the 64b transition, but left before that was finished.
