The Programming Model
Captions available
The idea
A programming model is designed for humans to read and write: a syntax of keywords, operators, and punctuation giving precise meaning, with the resulting text called source code.
In practice
A payroll program's source spells its rules in words and symbols a person can audit.
Where people slip
Precision is the entry fee — the syntax forgives nothing.
