Ephe-sysrpl
Ephe-sysrpl is a modified version of Ephe. Most routines have been converted to SysRPL, hence a faster program.
Just download to your HP49G/G+ the file ephe-version-lang.lib49. The library works exactly like the original Ephe, so please refer to the documentation of Ephe. Here are functions that differs with the original Ephe:
- Ephe-sysrpl is much faster
- Ephe-sysrpl is only provided with one language
- Entering a place which is a integer but given as a real number is correctly handled.
You should take care about not using Ephe-sysrpl with an "Ephe" directory created by the original version or any previous version of Ephe-sysrpl.
Ephe-sysrpl may have some nasty bugs, even if it works flawlessly for me. Backup your memory, you have been warned.

- Bug fix: Galilean satellites computing was totally wrong.
