- In the Selection section, this paragraph appears: "Returns a string which contains all but the last n characters of string."  However, there is no procedure above that paragraph, and n is not defined.  It appears to be an obsolete definition of string-drop/cursor.

- In the Copying and conversion section, the first two procedures take a parameter span, but the description uses string, which is consistent with the rest of the document.  (Why have two names for equivalent procedures, by the way?  That will be confusing.)
