Search TipsNamed List Methods
Named Lists are used to both pass and return lists of items to SIS Desktop methods, and exist only for the duration of a Cadcorp SIS Desktop session.
Named Lists are referred to by an application/customisation supplied textual name.
It is possible for the contents of a Named List to become out-of-date, e.g. if an Item 
in a Named List is deleted or if its dataset is removed. Any attempt to access an out-of-date Item will result in an error.
It is therefore best to use Named Lists as temporary storage, and it is good practice to empty them using EmptyList after they have been used.
