For testing purposes yes. The DIAGxx TRAP CsvRentSP252. >Why not? $$ >If just REFR is marked, then pages that are wholly contained within >the module may be page protected, but partial pages at the >beginning or end of the module are not protected. That is true whether you have REFR or RENT,REFR. >I tried loading a REFR-only module that was >page aligned and 3 pages long, and event though CDEPROTP=1 was set in >its CDE, z/OS insisted on loading the module completely in key-8 >storage. I don't see that. When REFRPROT is in effect and the module has the REFR option it will be placed into key 0 page-protected storage, not key 8 (assuming other environmental factors are true, the same as for will does not care about key). It page-protects. Not even key 0 can write into that using the virtual address (stores into "real" work). Dave C, send me a note offline and maybe we can figure out what's going on. At the least, I can show you what I tried and you can try that specific thing (or vice versa) Peter Relson z/OS Core Technology Design ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
