Nonexecuting

A nonexecuting program is the limp puppet without a hand, an empty shell. Slip a computer inside and it becomes a working software machine: an electric-powered information-transforming machine...

Program comments are nonexecuting statements that you add to a program for the purpose of documentation. Programmers use comments to leave notes for themselves and for others who might read their programs in the future.
