List Variable List Variable List Variable
A list is a series of items (numbers, expressions, or character strings) that may or may
not be related. Each item is called an element. In the Data/Matrix Editor, a list variable:
• Is shown as a single column of elements,
each in a separate cell.
• Must be continuous; blank or empty cells
are not allowed within the list.
• Can have up to 999 elements.
Ê
Column title and header cells are not saved as part of the list.
If you enter more than one column of elements in a list variable, it is converted
automatically into a data variable.
