I'm having a hard time understanding how arrays work in data structures. It seems that its possible to do any operations on them only if the at least one scalar was appended to the data list. Does that mean a [struct] consisting only of arrays is essentially useless? Also, how array objects in vanilla like [array size] and [array set] work with data structure arrays?

@Jovito I think that you will have to read through this........
I cannot find it in original form, but I don't think that I have changed anything
