This monitor object (see Section 5.4.14, “The Monitor Class”) holds the default output stream object (see Chapter 14, Input and Output Streams). This is the destination for output from the SAY instruction, the LINEOUT method (.OUTPUT~LINEOUT), and, if you specify no stream name, the LINEOUT built-in function. You can replace this object in the environment to direct such output elsewhere (for example, to a transcript window).

The default for this object's initial destination is the .STDOUT stream.
