duplicate() (list function)
Syntax
(
oldList
).duplicate()
duplicate(
oldList
)
Description
List function; returns a copy of a list and copies nested lists (list items that also are lists) and their contents. The function is useful for saving a list's current content.
When you assign a list to a variable, the variable contains a reference to the list, not the list itself. This means any changes to the copy also affect the original list.
To see an example of duplicate() (list function)
used in a completed movie, see the Vector Shapes movie in the Learning\Lingo Examples folder inside the Director application folder.
Example
This statement makes a copy of the list CustomersToday and assigns it to the variable CustomerRecord
:
CustomerRecord = CustomersToday.duplicate()
