Comments (GNU Algol 68 Coding Guidelines)

## 3 Comments ¶

Use `"foo"` to refer to formal parameters when documenting procedures or operators.

Use ``whatever'` to refer to any other source construct that is not a formal parameter.

Use `{{` and `}}` delimiters for commenting out code. Remember comments in modern Algol 68 are nestable.

Examples:

    int error_hash = 0;

    { Return a hash code for the string "s", or `error_hash' if the string
      is too long.  }

    proc hash_string (string s)

    {{ int no_longer_needed; }}
