[FX.php List] Difference in code syntax

[VanBuskirk, Patricia]

Can someone explain the difference between the following...


     $deptList = $deptListQuery->DoFXAction(FX_ACTION_FINDALL);   

                  OR

     $deptList = $deptListQuery->FMFind();



     {$Listing['PrintOrder']}

		OR

	$Listing['PrintLine'] [0]


I am trying to copy code from someone else and it is confusing me!

Thanks!
Trish
