If what you try is to write to a text file, here are some
lines to do so (note that $Stream actually contains the last
value bound to Stream):

?- open('test_file', append, Stream).

Stream = '$stream'(1148628)

Yes
?- write($Stream, 'One line').

Yes
?- close($Stream).

Yes
?- ls.
test_file

Yes


This can also be done using the following goal:
?- open('test_file', append, Stream), write(Stream, 'One
line'), close(Stream).

More info is in the manual section 4.16
