The delimiter page is the next page after
your search has stopped. It may or may not have a different page status
than the last page searched.
If the search goes on for the maximum number of pages (specified
in the second word of the parameter list), and still does not find
a different page status, then the address of the next page after the
last page examined is returned as the delimiter page. This page may
or may not have a different page status than the last page examined.
If the search finds a different page status before reaching the
maximum number of pages to be searched, the search is complete and
the address of the next page after the last page examined is returned
as the delimiter page. This page does have a different page status
(that is why the search ended).
If the search reaches the end of storage before finding a different
page status, the delimiter page will contain the address X'7FFFFFFF'.
The search may be terminated before the maximum number of pages
have been searched, or before a page of a different status has been
found and before the end of storage has been reached. In that case,
all pages up to the delimiter page have the same status and the status
of the delimiter page may or may not be the same as the previous page.
This
might occur, for example, when the page table for the delimiter page
has been paged out.
