The purpose of this program is to allow the user to view all of the waypoints that are linked by airways or direct legs to a selected waypoint. This enables the user to determine what airways use the particular waypoint, and what direct legs have been established.

The available modes are:

If there is no ambiguity, the country code and type fields will be filled automatically, otherwise the cursor will be positioned in the appropriate field and you will be prompted for input. The <?> Search function can be used to assist in the selection.
