Ephe-sysrpl

Ephe-sysrpl is a modified version of Ephe (by Jean Philippe Eimer). Ephe-sysrpl is the work of Khanh-Dang NGUYEN THU LAM (email: kdntl, domain=yahoo.fr). Most routines have been converted to SysRPL, hence a (much) faster program.

Just download to your HP49G/G+ or HP50G 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 (much!) faster.
• You cannot switch between languages with Ephe-sysrpl, while Ephe can. (For speed efficiency purposes and a smaller program.)
• 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.

I have never succeeded in crashing the calc while using Ephe-sysrpl. But as always, you should backup your memory before testing a new program.

Download and changelog

September, 26th 2007

ephe-2.13s0.zip (< 63 KB): syncing with the original Ephe 2.13 (bug fixing). I haven't tested this version yet.

February, 6th 2006

ephe-2.12s0.zip (< 63 KB): syncing with the original Ephe 2.12 (now handles any date format).

January, 24th 2006

ephe-2.11s2.zip

• There is now one file for each language. The program is smaller (around 62 KB), and much faster, as the translation routine slowed down all the library.
• Bug fix: rise/set of stars failed when the star doesn't rise or set
• Bug fix: Galilean satellites computing was totally wrong.
