Use Case of udiFirstListIndex: Navigating from the First to the Last Element in the List

Overview

This example illustrates how to navigate from the first to the last element in the list:

Illustration	Code Example
	//start from the first element of the list udiIndex := ifTargetsHandler.udiFirstListIndex; WHILE udiIndex <> Gc_udiTailListIndex DO //get the data on the target at the current index stTempTarget := ifTargetsHandler.GetTarget(udiIndex); //do something //get the NEXT index udiIndex := ifTargetsHandler.GetNextListIndex(udiIndex); END_WHILE

Illustration

Code Example

//start from the first element of the list
udiIndex := ifTargetsHandler.udiFirstListIndex;

WHILE udiIndex <> Gc_udiTailListIndex DO
    //get the data on the target at the current index
    stTempTarget := ifTargetsHandler.GetTarget(udiIndex);

    //do something

    //get the NEXT index
    udiIndex := ifTargetsHandler.GetNextListIndex(udiIndex);
END_WHILE
