Game Record Declarations

src/CIV.H defines the shared city, unit, unit-type and terrain records shown in the following pages. In this DOS game, int occupies two bytes and long occupies four.

Cities and units use compact records with byte-sized coordinates and status fields. Cities name their food and shield reserves, worked-tile mask, specialist types, name index, trade routes and stored garrison units directly. Unit f8 retains its provisional name and has uses including pathfinding direction.

Shared declarations are organized in headers named after the module defining the symbols. The function reference groups them by subsystem.
