2.7 Comments
- 1
- A comment starts with two adjacent hyphens and extends up to the end of the line. A comment can appear on any line of a program. The presence or absence of comments has no influence on whether a program is legal or illegal. Furthermore, comments do not influence the effect of a program; their sole purpose is the enlightenment of the human reader.

- Examples:
-- the last sentence above echoes the Algol 68 report
end
; -- processing of LINE is complete
