[] (access)


To access a specified element of a list by position use A_LIST[Index]. Index is the position of the element you want to access starting at 0, so the first element has index 0, the second index 1 and so on.


["First", "Second", "Third"][0]

This creates a simple list of three elements and returns the first one.

p is Person

This returns the first nationality a person has.

If the person has no nationalities this rule will fail. So if you don't know if a person will have nationalities at all add checks. E.g. check if the list is long enough:

if count(p.nationalities) > 0 then p.nationalities[0] else 'No nationality' end
