  37
  38     INPUTS
  39
  40     appName         --  the application owning the item stored in nonvolatile
  41                         memory
  42     itemName        --  the name of the item to change the protection of
  43     mask            --  the new protection status
  44
  45     killRequesters  --  if TRUE no system requesters will be displayed during
  46                         the operation of this function
