Abstract

In a double-indexed key system for extended addressing with multiple Address Space Index Stack (ASIS) images in storage, protection against invalid images is necessary. A method is described here to insure system integrity through limit checking on ASIS length via a parameter stored in the index stack register. Reference is made to the preceding article that is of interest.
