First question: what is in R0 for the storage obtain? Second question: what is in R8?
The PGSER invocation that you show in your post is incomplete and syntactically incorrect. I do not choose to guess what you left out. Please double-check your posts before you send them. If nothing else, you left out the end address which is rather important. Third question: what did you put into the end address? Fourth question: did you look at the generated code before posting your question? These are rather obvious questions to have provided answers for within your original post. You cannot be right that reg 7 "points to X'88' within that page", since subpool 0 does honor page boundary, so reg 7 (if it still contains the output from STORAGE OBTAIN) would point to offset 0 within a page.
