I was curious, and the IBM i whitepaper says that they do provide backwards compatibility, allegedly back to System/38. > When vendors start getting squirrelly about operating system names > and compatibility, I take it as "time to start over from scratch > with a new OS". I have never used AS/400, but I expected to be interesting because pointers are 16 bytes long, and conversion between pointers and integers is very limited. I wonder if they use the additional bits in the pointer representation to achieve memory safety for C programs, which would be a pretty unique feature.
