  40
  41     appName         --  the application owning the item stored in nonvolatile
  42                         memory
  43     itemName        --  the name of the item to change the protection of
  44     mask            --  the new protection status
  45
  46     killRequesters  --  if TRUE no system requesters will be displayed during
