It achieved that in a similar way to the JVM though, architecture-independent bytecode.
That said, it's still incredibly impressive that System/38 programs can run unmodified and without recompilation on modern POWER8 (soon POWER9) systems. Sadly not all software can be as well-architected as AS/400.
