*TRACE-OUTPUT* is a system variable that contains a file pointer that points to the file where all trace output goes to. The default file for *TRACE-OUTPUT* is the system standard error device - normally the screen.
*trace-output* ; returns #<File-Stream: #243de>
NOTE: *TRACE-OUTPUT*, *DEBUG-IO* and *ERROR-OUTPUT* are normally all set to the same file stream - STDERR.
