Params value is the object whose datatype you wish to coerce to be a direction.
Action Coerces the datatype of value to be directionType if possible.
See the discussion of datatypes in Chapter 1 of the UserTalk Reference Guide for details. The example above uses a special Frontier direction value that can be used to remove a previous setting for a direction, for example. The direction verb may prove useful in interacting with users who are being guided through navigating an outline. If the user supplies a string to indicate a direction he wants to travel, for example, coercing the string with direction would enable you to use any of the outline navigating verbs with the user's input as a parameter.
