Determines the name of the list element with the specified index.
Syntax
ListElementNames(List [ , Index ])
The syntax of the ListElementNames function consists of the following parts:
Part |
Description |
|---|---|
List |
The list from which the name of the element within is to be read. Permitted data structures are List. All data types are permitted. |
Index |
The index of the elements in the list whose names are to be determined. A scalar value addresses a single name and a data series addresses multiple names. Negative indexes index from the end of the list. The argument is optional. If you omit it, a data series with the name of all list elements is returned. Permitted data structures are Scalar value and Data series. All integral data types are permitted. If the argument is a list, then the first element in the list is taken. If this is also a list, then the process is repeated. |
Remarks
The elements in the list are numbered starting with zero. The result is a string with the name of the indexed list element or a data series with multiple element names of the list. If no element name is saved for a list element in the list itself, but the list element has header information, the name is taken from this information. If the list element does not have a name, an empty string is passed.
