CountList()

Syntax

Result = CountList(linkedlist())

Counts how many elements there are in the linked list. It does not change the current element. This command is very fast (it doesn't iterates all the list but uses a cached result) and can be safely used to determine if a list is empty or not.

Parameter:
linkedlist() - The name of your linked list variable, created with the NewList command. You must specify the brackets after the list name.

Return value:
The total number of elements in the linked list.

Example:

  NewList countme.w()

  ; Small loop to add some elements to the list.
  For i=0 To 10
    AddElement(countme())
    countme() = i * 23
  Next

  ; Show how many elements there are in the list. I hope you thought
  ; of the same value as this example ;)
  MessageRequester("Information", "There are "+Str(CountList(countme()))+" elements in the list", #PB_MessageRequester_OK)
