Create empty $list associated with image
Note: Many $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $ListNewI function is the New constructor.
$ListNewI creates an empty $list. The created $list is associated with an image exactly as if the $ListNew call was followed by a $ListImg call.
The $ListNewI function accepts two arguments and returns a numeric result.
Syntax
%result = $ListNewI(image_id, [option])
%result | A numeric variable set to the identifier of the created empty $list.
No error codes are associated with $ListNewI, though the absence of the image identifier or an invalid image identifier will cause request cancellation. |
---|---|
image_id | A string that contains the name of an image, or the name of any image item from the required image. |
option | Specifying the string NOREL indicates that the contents of the $list are not to be emptied when a Release All Records statement is executed. |
Usage notes
All invocations of a particular call to $ListNewI will always return the same value. Each time that call is executed, any previous $list created by that call is deleted, and a new list is created.
