G-Series, H-Series, and J-Series Guardian Procedures
The G-series, H-series, and J-series Guardian procedures each support a superset of the features
of the previous release series of the operating system. Some features of a specific release series
may not be available on the previous release series. As noted in individual procedure descriptions,
some procedures have been added, and some have been enhanced, from one series to the next
or from one Release Version Update (RVU) to the next.
For details on how to convert applications to use G-series Guardian procedures, see the G-Series
