DBG: OUTS (command) value (string)
Send a string to the debug log - use DBG: POLL to retrieve.
DBG: POLL (command)
This takes all of the DBG: OUTV and DBG: OUTS output to date and writes it to the output stream.
That is all I could find. Maybe you should mess around a little bit with it, such as running dbg: poll in the ingame console or something like that...
If you want to take the output stream of your own agents' scripts, I am not entirely sure how that works. You miiight need to use the CAOS command (CAOS has a command called CAOS)...
Also, if you do not have it already, you should definitely get yourself a Categorical CAOS Documentation. The alphabetical one is kinda useless when you use Ctrl-F inside the categorical to find stuff...
