working_directory(-Old, +New)

Unify Old with an absolute path to the current working directory and change working directory to New. Use the pattern working_directory(CWD, CWD) to get the current directory. See also absolute_file_name/2 and chdir/1.^{bugSome
of the file I/O predicates use local filenames. Changing directory while
file-bound streams are open causes wrong results on telling/1, seeing/1
and current_stream/3.} Note that the working directory is shared between all threads.
