Yes, that is what SYS$OUTPUT is.  By default it is a process-permanent
file so successive programs writing to SYS$OUTPUT all write to the same
version of the file (if it is on disk) rather than each creating a new
versions.  Of course versioning is irrelevant if the output is a terminal,
although it does matter if the output is to an ANSI magtape.

To what operating system do those results apply ?
