           Not reset-proof
           From KS2.04
           Bent vectors: LoadSeg
       Destruction: Depending on $ DFF009, a NOP in
           wrote the file. Since the original value and position are NOT
           to be saved, expansion does NOT make sense. Some different
           infected files are running. The majority create a guru. VT
           only offers delete.

       Memory anchoring:
           - FindTask bent - end
           - Examine bent - end
           - SnoopDos in memory - CCR is changed
           - Loadseg is bent
       Link operation:
           - Behind the 1st hunk with LoadSeg
           - length variable depending on one cell,
             that always changes its value (addition)
           - Always new coding with EOR and this cell
             value change
           - Findtask not changed
           - Examine not changed
           - Filename does not contain "." or "-"
           - Medium validated
           - 3 blocks free
           - File larger than 1024 bytes
           - File smaller NO limit
           - Search for RTS only in the last long word of the 1st hunk and
             Replace with NOP
           - Depending on $ DFF009 a NOP in the 1st hunk
           - Write back FileDate
       Recommendation: If you find linked files and original files
             have to play back.
             VTprefs / filetest requester according to df0: test
             Click all requesters.
             You will then have a list of all the files you have
             have to play again.
