       1mscanfile 22m?4m-copyfile24m 4mcopyFileId24m? 4mcontexthandle24m 4mfileId0m
              Scan  the  file  specified  by 4mfileId24m, starting from the current
              file position.  Check all patterns in the scan context specified
              by 4mcontexthandle24m against it, executing the match commands corre-
              sponding to patterns matched.

              If the optional 4m-copyfile24m argument is specified, the next  argu-
              ment  is a file ID to which all lines not matched by any pattern
              (excluding the default pattern) are to be written.  If the  copy
              file  is specified with this flag, instead of using the 1mscancon-0m
              1mtext copyfile 22mcommand, the file is disassociated from  the  scan
              context at the end of the scan.

              This  command  does  not  work  on  files containing binary data
              (bytes of zero).
