We currently have a prototype version of ABCL/1 available via .... I have recently finished a prototype implementation of OO||, an object oriented programming language / environment for distributed / parallel processing. It is in support of my phd dissertation. I will make it publicly available by the 1st of December (when I should be totally finished). The implementation supports distributed heterogeneous computing environments. Our test bed includes 30 SUN 3's,4's and Sparcstations, 1 Encore Multimax 6 Processor, 1 IBM 3090, 15 PS/2 70 AIX, 1 Cogent XTM and several plain unix boxes (vax, pyramid, att). The language supports inheritance, delegation, classes, activities, polymorphism, numerous reflective capibilities, object migration and modification, class modification, and a lot of graphics stuff (the main are of my research). In essence, I can bring up a windowing envt. such as X and see a console monitoring all objects in the system via machine nodes or software processes. I can use the mouse to move objects to different machines, inspect objects, change values of local state....etc. It runs fine, and looks good (subjective) and will be PD soon. /*----------- Thanks in advance... --------------------------------------+ | Peter C.

Bahrs | This sounds interesting to me. Could you provide more details, i.e. contrast the facilities to other distributed OO languages like, ABCL, BETA, ConcurrentSmalltalk, DistributedSmalltalk, Ellie, Emerald, POOL,...
