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 aren’t 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; }}
