"file" is not defined in that example. I think you meant to write f.open(),
f.writeln(), and f.close().

Replacing "file" with "f" in your example seems to work fine for me (creates a
file "test.txt" with the 2 lines you have specified).

Your code looks fine (except for the file/f confusion I mentioned). It might be
confusing to you that the file being created/written will be located in your
Synchronet "ctrl" directory since you did not specify a full pathname for the
file.
There are many examples in the exec/*.js files which open/modify files. You
could look at those for some tips or inspiration as well.
