More like multiple dialogs such as "Give me the item/Hello, who are you?/What was that explosion?" For NPC Dialogs and "Yes#No#What Item?/Harry the wizard#It's a secret#MrRodgers/An explosion#What?#Tnt"
Where to get the NPC dialogs and all responses you use index X and separator /; but if you wanted a response, you'd have to use index Y and separator # over the responses you just got.
Edit: The cool thing is that you are not blocked by the array being rectangular for example you could have the first dialog have 2 responses and the second 52 and it would be ok, whereas in a 2d array you'd have one of the columns with 50 free spaces or if you had a 1D you'd have to save the index or go thru the array to find the token to be able to access second dialog (which tokenat already does for you)
