The same way you do when you are faced with converting your code to bimodal AMODE31 - you don't write code like that, and it is not something that has an application-defined purpose that can't be dispensed with. > Admittedly IEFBR14 will work fine in AMOD64 > if the high 32 bits of R14 and R15 are zero. > However, if you have to deal with legacy > 24-bit code, then you have to deal with the > incompatibility between AMODE24 and AMODE64. The same is true of AMODE31. All I am asking for is that when someone goes to the effort of making their legacy AM24 application bimodal, they make it trimodal at the same time. BFN.
