Peter, While you have a "somewhat" valid point, I think that IBM did a much better job at backward compatibility with 31 <-> 64 bit than any others. In most other 64 bit os's, to run 64 bit, most applications have to be recompiled. A 64 bit process space CANNOT invoke 32 bit services (they just can't don't ask), so yes, while IBM could have done better, they did document the fact that return codes are 32 bit values, did they not? Just because some thinks make assumptions, the doc is clear.

I mean, aside from the sheer magnitude of the effort, which is NOT an excuse not to do it. Isn't this supposed to be a 64-bit OS? Why shouldn't ALL services of a 64-bit OS return 64-bit information codes? As part of the transition to a "real" 64-bit OS, why wouldn't it be the (or at least *a*) #1 priority to be sure all system interfaces were 64-bit-clean? I know, I know, "...waste of scarce developer resources..." -- but why are those resources so scarce? IBM is a multi-billion-dollar-profit corporation, so there is no fiscal excuse for scarce developer resources. And it's not like the talent is scarce either, it's just that we're closer to retirement age than makes HR departments happy. And we're not cheap labor either. </grumble-rant> Thanks for listening.
