        [Leif Svalgaard]  USRIDX or machine indexes are very fast.
        I use them all the time to very good effect. For some unknown
        reason IBM has removed support for machine indexes for
        program running in user state. You cannot create a machine
        index from a user state program at security levels above 30.
        I would be interested to hear from some of the IBM lurkers
        why that is.
