File specifications provide the system with the information
    necessary to identify a unique file or device. File
    specifications have the following format:

         node::device:[directory]filename.type;version

    The punctuation marks are required to separate the fields of the
    file specification. These fields are:

       node       Network node name
       device     Device name
       directory  Directory name
       filename   File name
       type       File type
       version    File version number

  $ COPY GREEN::DISK1:[JONES]BUSINESS_REPORT.TXT;4
  _To: BUSINESS_REPORT.TXT

      This example shows how a file is specified when using the COPY
      command to copy a file to the current directory from another
      user's directory on another node.
