Value for Item to return when Name has no value (FloatNamedArraylist, NamedArraylist, and UnicodeNamedArraylist classes)


Default is a ReadWrite property that specifies the value to be returned if both of these conditions are satisfied:

Syntax

%currentItem = anyNal:Default anyNal:Default = newItem

Syntax terms

%currentItem A variable of the anyNal item type, or one that can be converted to from that type; it will receive the current default.
anyNal A FloatNamedArraylist, NamedArraylist, or UnicodeNamedArraylist object.
newItem A new value that matches the anyNal item type, or one that can be converted to that type; that will become the new default.

Usage notes

  • The initial value of the Default property varies with the array list item type:
    Item typeValue
    Float and Fixed0
    String, Longstring, and Unicodenull string
    Objectnull reference
