Nested map usage example

[xvxx]

I'm sure I'm just missing something, but I can't figure out how to get nested maps to work.

Here is the example from https://docs.ldpl-lang.org/data/:

data:
    listOfMaps is text map list
    listOfLists is text list list
procedure:
    push map to listOfMaps
    store "Hello!" in toListOfLists:0:"hi!"
    # Pushes a map to listOfMaps and then stores
    # the value "Hello!" in the key "hi!" of the pushed map
    push list to listOfLists
    push "Hello!" toListOfLists:0
    # Pushes a map to listOfLists and then pushes
    # the value "Hello!" at index 0 of the pushed list

Obviously there is a typo as toListOfLists doesn't exist. But if I change it to listOfMaps:

data:
    listOfMaps is text map list

procedure:
    store "Hello!" in listOfMaps:0:"hi!"

This compiles but produces a runtime error:

$ ./ldpl map.ldpl
* Loading map.ldpl
* Compiling map.ldpl
* Building map-bin
* Saved as map-bin
* File(s) compiled successfully.
$ ./map-bin
Runtime Error: LIST index 0 out of range [0, 0)

Am I missing a step here? The documentation for nested lists works for me when I test it.

You need to add the push map to listOfMaps line, otherwise listOfMaps will be empty and you can´t access its first element (listOfMaps:0) because it doesn´t exist.

Oh, I was literally missing a line! Ha, I knew it. Thank you.
