** WARNING ** LiveCode ListProcessor is no longer being developed or maintained.
Simple list processing - first, last, next, prior, head, tail, ahead, behind, peek, poke, remove, append, insert, etc..
The current implementation of ListProcessor uses LiveCode arrays to store a list and its index. The design and code have not been optimised in anyway. My first objective is to get basic list processing working and then to improve on it.
This function creates a list. A variable in which to "put" the created list.
