The edit button toggles the crisp argument viewer between view and edit modes.
In view mode the window simply displays the argument as text.
In the edit mode you can edit the argument and its hyperlink.
A crisp argument is made up of any number of pairs of an operator and an operand. Each operator-operand pair is “and-ed” together to build the crisp argument. The argument is used to evaluate the data link's value. This editor presents the argument as a list of these operator-operand pairs.
Example: to report “true” when “distance” is less than 1000, the argument would be < 1000
Example: to report “true” when “distance” is between 500 and 1000, the argument would be > 500 AND < 1000
The above example is a “two part” argument meaning that is consists of 2 operator-operand pairs: > 500 and < 1000
