Example

If the names of the parameters in the DISP example were changed, the user's view could be preserved by specifying keywords as follows (Note: the example is not intended as an illustration of common practice - it is only to illustrate the principle):

INTERFACE DISP
   .
   PARAMETER P1
         .
      POSITION 1
      KEYWORD IMAGE
         .
   ENDPARAMETER
   PARAMETER P2
         .
      POSITION 2
      KEYWORD DISPLAY
         .
   ENDPARAMETER
   PARAMETER P3
         .
      POSITION 3
      KEYWORD LIMITS
         .
   ENDPARAMETER
      .
ENDINTERFACE

The user could then specify:

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

Note that keyword-style parameter specifiers are ignored in calculating position. Therefore, with the above Interface File, the same effect would be produced by the command:

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