(Specific counterexamples do not invalidate the point - we >are talking about the bulk of application software.) You don't see any value in writing AM-anything code into the future? Eventually everything will be AM64-clean and you will have a pure AM64 environment. Pure AM-anything ideally, which means not using negative indexes in 64-bit programs and expecting 64-bit wrap/mask. >Further: Nobody wants to go back and change all their programs so that >they can work in all these AMODEs. 1. When updating programs for unrelated reasons, they could be made AM-anything at the same time. 2. Anyone using a high-level language just needs the compiler to be AM-anything. Next time they recompile they will pick up the change. BFN.
