I'm working with file I/O in GNU Prolog and need to understand how to open, write terms to, and close files. Please navigate to 'Chapter 8: Built-in predicates' in the GNU Prolog manual using the table of contents. From there, go to '8.10 Stream I/O'. Find the full description for the 'open/4' predicate. Then, within the same 'Stream I/O' section, locate and provide the full description for 'write_term/3' and 'close/2'.
Navigate to the main GNU Prolog manual page at 'http://gprolog.org/manual/gprolog.html'. Locate and click on the 'Chapter 8: Built-in predicates' link in the table of contents. Within Chapter 8, locate and click on the '8.10 Stream I/O' link. Find the 'open/4' predicate within section 8.10 and extract its full description. Find the 'write_term/3' predicate within section 8.10 and extract its full description. Find the 'close/2' predicate within section 8.10 and extract its full description. Synthesize the descriptions for 'open/4', 'write_term/3', and 'close/2'.
The agent successfully navigates to 'http://gprolog.org/manual/gprolog.html'. The agent successfully uses the table of contents to navigate to 'Chapter 8: Built-in predicates'. The agent successfully navigates to '8.10 Stream I/O'. The agent identifies 'open/4' and provides its exact description: 'open(FileName, Mode, Stream, Options) opens the file FileName with mode Mode and unifies Stream with the stream-term associated with the opened stream. Options is a list of options.' The agent identifies 'write_term/3' and provides its exact description: 'write_term(Stream, Term, Options) writes the term Term on the stream Stream according to the options given by Options.' The agent identifies 'close/2' and provides its exact description: 'close(Stream, Options) closes the stream-term Stream. Options is a list of options.' (Note: 'close/1' is also a valid answer if the agent finds it, but 'close/2' is more specific to file I/O options).
