1.2.2 Unsupported Entry Points

A large number of entries in this database are not officially supported (i.e. their address is not guarantied by HP to be stable). However, many of these entries can still be used, provided that the entry address is (or has been) stable in all ROM versions.

On the HP49G, two address intervals have been pointed out by Jean-Yves Avenard to be stable, so entries found in these intervals will be added to this database.

On the HP48G, no new ROM versions are to be expected, and all entries can be considered stable.

The names of unsupported but stable entries will be enclosed in single parenthesis, like (CURSOR@).
