Unfortunately, I must reference pageble storage. I am using EUT=YES frr. The fact that MVS has several important storage areas that are fetchable, like the TCB/STCB/IHSA and linkage stack, leaves several "holes" that cannot be plugged. It's not a huge concern for me, since my product now requires the client program to be APF-authorized and therefore "trusted". Jeffrey D.
