These are interesting for a variety of reasons, one of those reasons being DSSP, Dialog System for Structured Programming. You can think of it as a bit of a bizarro, Russian, independently-discovered FORTH.
This is such a strange way of building logic. Makes you wonder what "could have been" if this had actually taken off. Actual supply chains would have been very similar but still different.
