One example would be, if I set up some conversation, or event, then I can have it dependent on what level a character is. Perhaps an NPC that only gives information to female characters. Perhaps some bonus is only given to members of the Harpers. As it is, I can change the macro with the formula I originally wrote. I can only have one negative value for all the macros I write this way. I am setting up an interactive type of city. With the extra number I can set up all sorts of adventures. I need to be able to insert an extra number to make the macro I made fully functional. As is the only possible negative value is zero. I want to make it so that when the boolean is zero, it triggers the macro #01.
