This is the header file of my simulation of life, the universe, and everything in a cellular telephone system as I wrote it in 1984. It was preceded by another header file declaring IMPLICIT data types and assigning array sizes.
The primitives here are cells (C), antenna faces (F), groups or logical faces (G), cell neighbors (N), radios (R), populations sets (P), terrain data sets (T), mobile telephone calls (M), X positions (X), and Y positions (Y). Each of these have attribute arrays described along with their COMMON declarations.
This collection of primitves and attributes became the bottom layer of other applications that displayed simulation output data and made recommendations of system parameters.
What I find most striking as I look at this header file is how similar it is to the programming I have done in the two decades between then and now. I have solved myriad different problems but the programming vocabulary here has remained sufficient to satisfy me.

c Besides being the COMMON part for the M2 simulation
c of life, the universe, and everything in a cellular
c system, this program documents the entire data base
c for all my cellular engineering programs.

c NAMING CONVENTIONS:
c First letter is variable type:
c integer = i through n
c floating point = a through h and r through z
c one-byte integer = o through q.
c Arrays generally start with f, n, p, or q
c where f indicates floating point,
c n indicates integer,
c p indicates a power or path loss byte, and
c q indicates a one-byte variable.
