I am a new GNU Prolog user and need to understand how to perform basic file input/output operations. Please navigate to the 'Built-in predicates' section of the GNU Prolog manual. Find the section related to 'Stream I/O' or 'File operations' and identify the predicates used for opening a file for writing, writing a term to a file, and closing a file. Provide the names of these predicates and a brief description of what each does.
Navigate to the main GNU Prolog manual page at 'http://gprolog.org/manual/gprolog.html'. Locate and click on the link for 'Chapter 8: Built-in predicates' (or similar, typically section 8). Within the 'Built-in predicates' section, search for 'Stream I/O' or 'File operations' or similar subsections. Identify the predicate for opening a file for writing (e.g., `open/4`). Identify the predicate for writing a term to a file (e.g., `write_term/3` or `write/2`). Identify the predicate for closing a file (e.g., `close/2`). Extract the names and brief descriptions of these three predicates.
The agent successfully navigates to the 'Built-in predicates' section. The agent identifies `open/4` (or `open/3`) as the predicate for opening a file for writing, and provides a description of its function. The agent identifies `write_term/3` (or `write/2`, `put_char/2`, etc.) as a predicate for writing a term/data to a file, and provides a description of its function. The agent identifies `close/2` (or `close/1`) as the predicate for closing a file, and provides a description of its function.
