Suppose that the user has given the command:INTERFACE DISP . PARAMETER IMAGE . VPATH PROMPT PROMPT 'Image to be displayed' . ENDPARAMETER PARAMETER DISPLAY . VPATH PROMPT PROMPT 'Image display device' . ENDPARAMETER . ENDINTERFACE
The program will take the specified value as the value of the IMAGE parameter. When it requires the DISPLAY parameter value, none has been specified on the command line so, as the VPATH field specifies that the user is to be prompted for a value, the system generates a prompt line such as:disp image=iue.image.swp2099
to which the user has to reply with a suitable value. (The prompt may also have a suggested value for the parameter, obtained via the PPATH field, see below).DISPLAY - Image display device >
