I didn't ask for it yet because the first step is to just have RM32 memory available. If I can at least have RM32 memory I can still switch to AM31 prior to executing READ. > I think that you are assuming that is is trivial. Yes, all I want them to do for READ is to test the current AMODE, and if it is 64, to do a BSM to AM31, and run the rest of READ as AM31 and then restore AM64 on return. Maybe 10 lines of code that disadvantages no-one. > Are you also assuming that they will accept an > address above the bar for parameters? No, I am expecting all data to have been allocated with RM24 or RM31 as currently documented by READ etc. I have no interest in putting OS-related data above the 2 GiB bar, and I have limited interest in putting the load module above the 2 GiB bar. I'm only interested in putting *application data* above the 2 GiB bar. BFN.
