Example

The previous example is therefore better written:

INTERFACE DISP
   .
   PARAMETER IMAGE
         .
      HELP 'This is the name of an image dataset to be displayed'
         .
   ENDPARAMETER
      .
      .
   PARAMETER LIMITS
         .
      HELPKEY 'DISP_DIR:DISP DISP PARAMETERS LIMITS'
         .
   ENDPARAMETER
      .
ENDINTERFACE
