Re: How to redirect stdout

[Alexandre Saidi]

Thanks Lindsey,
I've been trying any thing I could to make it work.
Ther's no way !
As I said, I saw a mail in the FAQ saying that stdout is not affected by 
set_output.
I'm using the version 1.2.16.
Perhaps ther'is is a trick withe the interactive mode ?

Thanks any way.

Here's what I do under prolog (for a test) :
address@hidden:~> gprolog
GNU Prolog 1.2.16

| ?- [user].
compiling user for byte code...
toto :- true.

user compiled, 2 lines read - 207 bytes written, 4104 ms

yes
| ?- open(fichier,write,F), current_output(Old), set_output(F), listing, 
flush_output(F), flush_output, close(F).

toto.

F = '$stream'(2)
Old = '$stream'(1)

(1 ms) yes
| ?- halt.
address@hidden:~>

The file 'fichier' is empty.
I've done many other tests with no success.
