Syntax Notation[edit | edit source]
The form of a King program is described by a formal syntax and semantic rules.
The chosen formal syntax is broadly inspired by Ada RM section 1.1.4 "Method of Description and Syntax Notation".
One change is that terminal symbols are represented in bold (not surrounded by ').
