Example

Again taking our DISP example, if the positions were specified as follows:

INTERFACE DISP
         .
   PARAMETER IMAGE
         .
      POSITION 1
         .
   ENDPARAMETER
   PARAMETER DISPLAY
         .
      POSITION 2
         .
   ENDPARAMETER
   PARAMETER LIMITS
         .
      POSITION 3
         .
   ENDPARAMETER   
      .
ENDINTERFACE

and the user gives the command:

disp iue.image.swp2099 ikon [1,511,255,512]

Then the HDS object iue.image.swp2099 would be associated with parameter IMAGE, XWINDOWS would be used as the DISPLAY and LIMITS would take the value [1,511,255,512].
