Nul : A Navigational User'S Language For A Network Structured Data Base

Summary: NUL: navigational language for a network-structured DBTG-like. Nonprocedural, hierarchical navigation via context-definitions and labelled links; separates entity designation from actions, enabling top-down traversal for non-programmers. (summarized by gpt-5-nano on Feb 09 2026)
