List Structures

A list structure allows CA Top Secret to control what is placed in the coupling facility and the maintain the data once it is there. The primary list structure, defined by the systems programmer, is used to hold all the data for the CA Top Secret database. The optional alternate list structure is used if something happens to the primary list structure. If no alternate is defined, and the primary is unavailable, CA Top Secret defaults to its current I/O processing.
