  /DATA
  /NODATA

   The /DATA qualifier is used to enable data display mode by
   default.  Certain commands are able to display data present
   in buffers and/or silos.  In order to reduce the amount of
   information on the screen, these commands do not display
   this data by default.  They do, however, have the /DATA
   qualifier to enable such output.

   The /DATA qualifier, when used on the TCPIP command WITHOUT
   a command verb, will enable (or disable) the default /DATA
   qualifier.
