Apply Simple syntax for addr where there are 3 lines

[Dakinejo]

What is the 'Apply Simple' syntax when creating a MicroStrat attribute where the source has 3 addr lines.
Sample I have is:
ApplySimple("#0|| ' ' ||#1", [NAME_LAST], [NAME_FIRST])
As stated there are 3 addr lines, addr_ln1, addr_ln2, addr_ln3. Question how is the applysimple constructed?
If addr_line2 is in the middle will there be a concat on either side? Is there a more efficient way of doing this?
