; Dig Dug II (U) [!] application-specific RAM aliases - Pass 1 ; Generated from every direct zero-page operand in reachable code: ; ref counts are reads/writes, `where` lists the referencing addresses. ; ZpXX names indicate storage with a role not yet unique enough for a behavioral name; ; Pass 2 replaces them with names derived from observed usage.
