List/Set[N]

Elements in lists, sets, may be extracted with the bracket operator:

$MyList[1] 

This has the same effect as .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".
