Tim Ed here. Just wanted to say thanks for the help I received from your program. You have no idea the struggle to store data out on the 49G's SD card using the information in print for the 49G. There is a brief note about using the :3: to reach the SD memory.
I have a couple of questions; is it possible to determine how many objects are stored on the SD card? and is it possible to simulate a key stroke in a program? ( I know that ON and F6 pressed together will bring up a menu and that preesing 8 will give battery condition and a hex value for the voltage but how to use this.) Any help will be really appreciated. Thanks again. Ed Von Essen
ps I'd rather be inside doing this today. 92 out on my back prorch. VE

Here is a program that will prompt for your note, and then store the
data into a dated file on the SD card in a folder called RESEARCH.
Each day will be in a new file, and each line will have a complete
timestamp. Here is an example of the exact text you find on the SD
card in a file named "4.092008.TXT" (the funny stuff at the beginning
can easily be erased in a text editor - it helps the calculator
identify it as a plain text file).

TESTING -- WED 04/09/08 10:10:08A
RUN AWAY LITTLE RABBIT!!! -- WED 04/09/08 10:10:38A
Begin program:
<< "Enter Profound Notes" { \Ga } INPUT " -- " + DATE TIME TSTR
+ 10 CHR + "RESEARCH/" DATE + ".TXT" + "3" ->TAG DUP
IFERR RCL THEN DROP STO ELSE ROT + SWAP DUP PURGE STO END >>
The \Ga means greek alpha character. This locks alpha mode on during
entry. The storage will automatically create a new file for the data
on the next day as needed, and all notes on the sane day are appended
into the file. This program could be easily edited and improved
depending on your needs.

Depends on how long you are using, but it can be anywhere from a week
to a month depending on usage. Note a week is about what I get on
mine while I am doing heavy programming/ flash memory writes for around
6-8 hours a day. Your usage would probably be much less and so I'd
guess more around the month range.
Where are you going to be? Is ruggedness an issue? If so, you might
want something that can survive being dropped out a 4th story building
onto concrete, will take a hollowpoint .22 bullet at 100 feet
(depending on where you are going that could save your life. . . ;-),
is completely weatherproof, floats on water, AND gives you the ability
to use 4-AA batteries which will give you several months of battery
life. Only downside is about a x3 increased weight of the bare
calculator and about a x2.5 volume increase. The cost is also more
than the calculator itself as we are still trying to pay off the cost
of the steel injection molds, but I could probably work out a deal if
needed. The first link is to the main page where you can see the unit
all put together, and the second is just the box.
