KM8: Using Dictionaries

Continuing the discussion from Store Values in Dynamically Created Variables?:

You can the Set Dictionary Value action to set an entry from those three things. I would be temped to use the Index variable as the dictionary name itself, then. Then the keys would be simple strings. So things like: [image] Then you could iterate through the dictionaries, restricting it to ones that start wi…
