But not any address-space-related subpool such as 229,230,249. The only storage that persists past the life of an address space is common storage. You need storage in CSA or SQA or above the bar common.
<snip> I want to make sure the Global storage is protected and can not be overridden. </snip> I don't know what you mean by "cannot be overridden". It can be overwritten by anyone in the right key. It could be freed, maliciously or inadvertently, by anyone with suitable authorization. Common storage just cannot be freed by an unauthorized program, and assuming it is in a system key cannot be written into by an unauthorized program. <snip> I understand I can use the ECVT but </snip> Assuming you mean the area pointed to by a slot in the customer anchor table pointed to by ECVTCTBL, there is no "but". It's still common storage.
