Output stream

The output stream in CAOS is where the output from any CAOS commands, most notably OUTS and OUTV, goes to. It may be directed:
 * in an externally injected script, to the calling process,
 * within the CAOS command, to a string which is eventually returned to the calling script,
 * within game scripts, nowhere,
 * after FILE OOPE, to a journal file.
