The thing I like to most in my calculator is the possibility to do
some calculations without using my PC.
For my job I have to create some system performance reports that I
create working with csv files created by the processing system.

I am able to load these csv files on my 49G+ as strings and my program
parse the file, do some calculations and create a report table I send
to my desktop pc to create a report.

I like to use the HP for this because I can do dates calculation with
ease, feed list and matrix quickly. Please also consider that the RPL
language is the one I know the best.

My problem arise when I had to load a file of 800KB... Not enough
space in the calculator. Even if I had a card reader to put in on the
SD card, I couldn't put the 800KB string on the stack to be parsed...

Is there any chance I can extract smaller portions of the file without
having to recall the file in the stack?

I would like to avoid to manually chunk the original file, modify my
program that check for the total number of records and so on...

Any idea? 

Thank you very much.

If you figure this one out... please let me know.

I guess this could be done in ARM assembly by someone who knows how the
internal parts of the 49 are, basically by noone on this group except maybe
Jean-Yves or Cyrille but I doubt they would do it.

I've often thought that the card reader would be of great use if it
there were user rpl commands that could be used to perform file I/O
(e.g. C run time file handles).  The amount of ram that is available
is plenty to parse a lot of file data and process the desired
portions.

Hello Arnaud,
   maybe it's too early for your approach. Anyway I think that it
could be useful to a lot of people.

I was dreaming also about having a RPL pc compiler that create code
that can run on my pc but this is another story. I would pay for it...

Have a nice day,
