term_string(?Term, ?String)
Bi-directional conversion between a term and a string. If String is instantiated, it is parsed and the result is unified with Term. Otherwise Term is‘written’using the option quoted(true) and the result is converted to String. If String only contains white space and/or comments, an syntax_error(end_of_string) exception is raised.
