Check out the "open" function:

http://www.jessrules.com/jess/docs/71/functions.html#open

Here's an example of what it would look like:

    (open myfile "output.txt")
(printout myfile " My message " ?*var1* "with variable to say.." crlf)



You just open a file, then write to it.

Hi friends,

I developped a expert system based on jess, but I need to generate my
informations from screen (by printout command) to file. Example:

<Jess code>
 .
defglobal ?*var1* = " **in file** ")
 .
defrule...

(printout t " My message " ?*var1* "with variable to say.." crlf)

I need that the message above says in .txt file and open the .txt file then
output as follows:

 -------- Test.txt ------

  My Message ** in file** with variable to say...

The question is: Is possible to create it ?? If possible a example for me
please ?

Thanks for advance,
