I did inspect it, and proved to myself that I had no idea what it actually does. :-) I do think the intent was that it returns the equal result, but that isn't documented anywhere (although it might be in the super-secret manual -- nobody reads that, including me. :-) > Has EQUAL changed since Ada 83 days? Just curious. I don't think so. The change log consists of lots of entries "Updated ACATS version string to "3.0"". The last substantive change is some functions added in June 1995; no changelog entry mentions Equal. >> I suspect that there are lot of tests that might fail if the rules for >> valid >> values are taken to the limit -- any test that intentionally raises an >> exception is always at risk for optimization problems (and that is what >> 13.9.1 is ultimately about). > > Yes, and I'll bet an agressive implementation of 11.6 would find some > wrong ACATS tests. That of course has happened a lot in the past. Fewer implementors are reporting anything these days, which probably only means that there is less active implementation. Randy.
