/sys$common/syshlp/helplib.hlb DELETE, /CHARACTERISTIC, Example  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  $ DEFINE/CHARACTERISTIC BLUE 7
     .
     .
     .
  $ DELETE/CHARACTERISTIC BLUE
  $ DEFINE/CHARACTERISTIC BLUE_INK 7

      The DEFINE/CHARACTERISTIC command in this example establishes
      the characteristic BLUE, with number 7, to mean blue ink
      ribbons for printers. To change the name of the characteristic,
      enter the DELETE/CHARACTERISTIC command. Then enter another
      DEFINE/CHARACTERISTIC command to rename the characteristic to
      BLUE_INK, using the characteristic number 7.
