       /OUTPUT[=filespec]

    Specifies the name of the file to which your PAK replica is
    written. If you do not specify the /OUTPUT qualifier, or if
    you do not supply a file specification with this qualifier, the
    output is sent to SYS$OUTPUT.

    If you specify a file name that already exists, this command
    creates a new version of the file. If you specify a complete file
    name and version that already exists, this command appends the
    PAK replica to the existing file.
