Hint Parameters

A special feature hides parameters. If a hidden point is chosen as a macro parameter during the generation of the macro, and if that point is associated to a point generated during the parameter selection when the macro is used, this new point will be hidden after the macro has been run.

This feature makes it possible to use points as hint parameters. An example would be a macro, which generates an equilateral triangle on a segment. The hint would be a third click indicating either side of the segment. In this case, an expression must be used for one of the 60 degree angles involving the third point, something like "60*sign(180-a(P,A,B))".
