To Specify Attributes Without Specifying Text

When you specify text-buffer, it must always be the second parameter in the call. attribute-buffer must be the third parameter in the call. Therefore, if you want to specify attributes without specifying text, you must set up a dummy parameter as the second parameter in the call. The dummy parameter can be any variable. The syntax to specify a dummy parameter is as follows:

call "PANELS" using panels-parameter-block
                    dummy
                    attribute-buffer
