A program uses the IARV64 PAGEOUT request to tell the system that the data in certain pages will not be used for some time (as measured in seconds) and that the pages are candidates for paging out of real storage. A pageout does not affect pages that are fixed in real storage. On the RANGLIST parameter, the program provides a list of page ranges. Authorized programs can use the ALETVALUE parameter to designate memory objects in the address space identified by the ALET.

A program uses the IARV64 PAGEIN request to tell the system that it will soon reference the data in certain pages and that the system should page them into real storage if the pages are not already backed by real storage. Authorized programs can use the ALETVALUE parameter to target pages of memory objects in the address space identified by the ALET.
