Abstract
A sectioned ordered queue in an information handling system comprises a plurality of queue sections arranged in order from a first queue section to a last queue section. Each queue section contains one or more queue entries that correspond to available ranges of real storage locations and are arranged in order from a first queue entry to a last queue entry. Each queue section and each queue entry in the queue sections having a weight factor defined for it. Each queue entry has an effective weight factor formed by combining the weight factor defined for the queue section with the weight factor defined for the queue entry. A new entry is added to the last queue section to indicate a newly available corresponding storage location, and one or more queue entries are deleted from the first section of the queue to indicate that the corresponding storage locations are no longer available. Various processes associated with a real storage manager are responsible for keeping the queue sections in balance, updating the queue sections, and removing entries from the queue to 'steal' real storage frames.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
