NONE, NADA, ZILCH. But the code path taken is only done with PSATOLD = zero. There are two of us here who say this is impossible (I'm one). But here we are, and we have seen this at 1.7, 1.9, and 1.10 (that I know about). And it is only here and there. So there must be some other way for PSATOLD to be zero. And that's all I'm asking: SRB does it, what else does it? Do IRBs? Because we do use IRBs from time to time (we do use VTAM).
