You create an instance of FileStream and then write to that. As in
fs := FileStream write: 'TheFileName.txt'.
[ | x |
x := 100 factorial.
fs
nextPutAll: 'The factorial of 100 is ';
print: x;
cr] ensure: [fs close]
The #ensure: block is not really necessary but makes sure that if there
is an error in your code you are not left with dangling open files.
Without the #ensure block you could just have
fs := FileStream write: 'TheFileName.txt'.
x := 100 factorial.
fs
nextPutAll: 'The factorial of 100 is ';
print: x;
cr.
fs close
