IMHO the fundamental error was making storage protect optional.

Protecting this storage will break myriad programs, and adding a subsystem or service to provide controlled access would be a huge undertaking, both for IBM to implement and for customers and ISVs to use. I would predict that even if IBM did it, people would turn it off so they could get work done. (Think early days of Windows UAC-and yes, that got better, but with significant investment in/revamp of Windows, plus it's mostly transparent to programs. Not the same thing, just similar in that folks just turned it off because it was too intrusive.) Put another way: this is arguably a fundamental design flaw in OS/360. At this point, it's not fixable. ...phsiii P.S. There's gotta be a joke about "Marx" Zelden and universal access to low core in there somewhere! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
