C for the Palm Pilot
Tested on Documents To Go 7.006
and on 10.0020 and the graphics on
the Palm are supported, for example in
the EOT astro sheet and the figure of 8
analemma sheet. Click the graph
button below the spreadsheet cell data
entry area.                                    
 
The illustrating-shadows.xls
spreadsheets have been
reworked for
PDAs, specifically the PalmPilot. The
vertical decliner spreadsheet is shown
to the left on a Palm T3.  
See notes
above for PalmPilot hotsynch using
win64 Windows Vista
 

Display output has been reworked,
hyperlinks removed and the sheets
adapted for their removal, changes in
formulae not supported by Documents
To Go, size changes, and so on.

A collection of spreadsheets ready for Documents To Go or Quick Office
on a PDA   
  (this is also to be found in the Excel page)
Excel for the
PalmPilot    (great on
the PC too !)
The actual programs on this
web site show not only the
graphical depictions, but also
the tables of hour line angles.
CAUTION: Windows Vista does not
support the Palm PDA by USB or WIFI
hotsynch. It should hotsynch with Bluetooth, I
finally got it to work but I am not sure how. It
took a couple of restarts, and turning things
on and off. Then Vista asked for a code, the
PDA also, and all sorts of permission. It did
finally synch.
See here. However, since then
not much luck. This is one of the many
mysteries of the universe.

the main web page for the latest PocketC is here
an earlier version with less features is also available

(this is also to be found in the C page)

FREE ~ One compiler version is free, the other is much updated, has a
45 day trial, and is available for a very reasonable cost.

This file has the documentation and the source code for a h-dial and
v-dial programs, some text output, some text and graphics, also a nice
almanac where you enter the month and day, it gives you EOT, decl,
hourly azi and alt, and sunrise/set data.  AND a
vertical decliner! AND an
EOT and declination for 4 days on either side of a given day in a given
month. Some are packaged as xxxxx.prc
executables (the xxxxx.pc is the
IDE source code), some are compiled on PocketC on the PDA and
executed from PocketC. In other words, two dials, two types of output,
and two ways of running the programs. It is so simple that I did not add
lots of notes. These dial programs work and have been validated, and
you can amend the code for other dial types.   
 

PocketC notes are here, and the zip file with those notes and the C
program for h and v-dials for the PDA are here
