True but irrelevant; those were two implementations of the same language, while bash and zsh are different languages. > It's perfectly fine to skip commenting on every discussion, It's perfectly fine to comment on what people actually write; it's not so fine to comment on what only exists in your head. -- Shmuel (Seymour J.)

I'm feeling a bit puzzled here! Bash doesn't come pre-installed with z/OS; rather, it's a tool ported by Rocket, so there shouldn't be any compatibility problems, right? If IBM decides to include zsh, which is considered superior to bash, this could be a game-changer. Once IBM introduced their Python SDK for z/OS, Rocket's Python started struggling and eventually became obsolete.
