How are case selection conditions stored and saved?

Global case selection conditions (definitions of subsets of data) are attached to a spreadsheet and are called Spreadsheet Case Selection Conditions. They are accessed from the Tools - Selection Conditions menu or by clicking the status bar field Sel. Analysis/Graph Case Selection Conditions can also be locally connected to an analysis or graph. They are accessed by clicking the Select Cases button that is available on all analysis/graph definition dialogs. You can save and open either type of selection conditions (and maintain libraries of case selection conditions) using the Open or Save As buttons in the appropriate Case Selection Conditions dialog. Note that case weights are specified in a similar manner.
