BREAKYES
When multiple index parameters are specified with the BREAK=YES sub-parameter, the BREAKYES parameter can be used to determine how these multiple index parameters are interpreted. They can either be logically ″AND’ed″ or ″OR’ed″ together.
When BREAKYES=AND is specified, the multiple index parameters with BREAK=YES are all ″AND’ed″ together. All index values must change for the current page to be considered the start of a new document.
When BREAKYES=OR is specified, the multiple index parameters with BREAK=YES are all ″OR’ed″ together. A change to any index value causes the current page to be considered the start of a new documentation. If a value other than AND or OR is specified for this parameter, an error message is issued and processing stops.
