List/Set[itemNum]
sourceNum is the zero-based item number in the referenced List or Set.
Elements in lists, sets, may be extracted (referenced) with the bracket operator:
$MyList[1]
This has the same effect as List/Set.at( ), but may be more convenient. Both
$MyList[1]
$MyList.at(1)
Returns the second list item (as list item addresses are zero-based).
This syntax can also assign values to specific elements of lists. For example,
$MyList="apple; pear; plum; cherry";
$MyList[1]="persimmon";
Will replace "pear" with "persimmon".
