..well, here we go - I just was told that you CAN have postscript viruses
and that they exist!:-) The simple trick is - there is a postscript
command to call an external programme... But you cn always tell
ghostscript:
     -dSAFER
          Disables the "deletefile"  and  "renamefile"  operators
          and  the  ability  to open files in any mode other than
          read-only.  This may be desirable for spoolers or other
          sensitive  environments  where a badly written or mali-
          cious PostScript program must be prevented from  chang-
          ing important files.
.. so, did (Sun-Solaris-)dvips produce a postscript file, that contains a
MSW virus?:-))))
