Including and Excluding Radio Buttons
All filter dialog boxes contain an Include and an Exclude radio button. These buttons are mutually exclusive. The Include/Exclude selection becomes part of the filter definition, and appears as part of the filter description displayed to the right of the Toolbar.
Include: A filter constructed with the "Include" button selected, returns a data set that includes frames that meet the conditions defined by the filter and omits frames that do not.
Exclude: A filter constructed with the "Exclude" button selected, returns a data set that excludes frames that meet the conditions defined by the filter and consists of frames that do not.
