I don't understand what "reuse" has to do with the conclusion. What am I missing? Whether or not the operating system reuses WEBs, you must not change them. The WEB is not a programming interface even for "read". It is a fair statement to make that no system control block fields other than those designated as programming interfaces should be changed. And it is also a fair statement to make that most programming interfaces are provided for read-only (although, I'm sorry to say, that has not been made clear enough). I hope no one, for example, is changing PSATOLD or PSAAOLD just because they are marked as programming interfaces !! Somehow the user community is expected to know this.
