What does the statement 'pageno=' accomplish in SAS programming?

The statement 'pageno=' in SAS programming is used to control the output of a report by setting the starting page number for future output. When you specify 'pageno=', you define the page number from which the subsequent output will start. This feature is particularly useful in generating reports that may have a specific format or requirement to start at a given page number, allowing for better organization and presentation of the output.

Understanding this functionality is essential for effective report generation in SAS. It helps ensure that reports are structured in a way that meets scholarly or business needs, particularly when dealing with printed documents or paginated outputs.

The other options relate to different functionalities in SAS. For instance, setting the first or last observation to be read deals with how datasets are accessed, whereas determining the number of lines in the output pertains to the output formatting rather than page management.
