'Palm Universe' is a star chart program for PalmOS. This is a freeware covered by the GNU General Public License. Please install PUniv.prc and four PDB files (Star, Line, Misc, and Desc). For Japanese descriptions, you can install the PUniv-DescDB(jp) file instead.  To minimize drawing time, I omitted constellation lines of several major constellations in the southern celestial hemisphere.  This palmware needs 'MathLib' library, which is provided on the web. You need also MathLib.c and MathLib.h if you recompile.  Thank you for your downloading.

This palmware switchs private records to be hidden when the device is turned off. Just tap it after installation. This very small program works a lot for me.
