ABSTRACT:
A report is generated in an object oriented software environment. A report iterator and a data iterator must have communications there between. The report iterator includes a report group header, a report group body having at least one report field, and a report group footer. Dependency is created between the contents of the report fields and an attribute of the current object. As a result of the communications established, a plurality of objects are stepped through sequentially. The dependency system is signalled each time the current object has changed. Each time the current object has changed, a new value is sent to a report field in the report group body.
