User-Defined Variables and Filters Toolbar
You can change the order of user variables in the list using the arrow buttons in the toolbar. You can define new variables with reference to each other, and they are added to the data in turn, in which case you can use the up/down arrows to reorder variables in legitimate sequence. See Sequence of Variables in the Data Editor Tutorial for an example.
