Indicate whether to use default runtime parameter attributes or new ones. These parameters are passed to the MIDlet(s) at runtime.
Use this option if the default runtime has the desired parameter attributes. Default runtime parameters are set on the Run|MIDlet page, found under the menus Run|Configurations and Project|Project Properties.
Use this option to enter new parameters if the default runtime does not have the desired parameters Click Add, then enter a parameter name in the first column followed by a parameter value in the second column.
