A Modest Proposal: o Retain page data set frames for REFR modules indefinitely. o When a main storage page of a REFR module is reassigned and a page data set copy exists, don't write it again. Do it! Programmers will learn quickly enough and paging I/O will be optimized. And programmers will beg for REFRPROT. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
