There is a program for PC called NoteCenter. You can find a copy of
this program here:

I need a program that works in the same way for Psion Revo. I need to
use the same file format to store its entries and have same basic
functions so that I can copy my note files from PC on to Revo and be
able to use them with out converting anything.

I know that it seams like a lot, but as a web programmer I know that
it could be realistically done in about 2-3 hours of coding. It is
just a simple text editor that stores its notes in a tree structure.
The only hard part of the project is parsing the NoteCenter file. But
the file is standard html file with html tags separating different
notes. I actually designed a program like that before in PHP. And
could probably make one in java. So why don't I do one my self. Well
for me it would take some time to learn all the tricks of programming
for Psion platform and buy books and such on the subject. On the other
hand an experienced Psion Programmer can probably finish it up in 2
hours with no problem. I just need a copy, so what ever you do to the
code after that is up to you, sell it, give it away, what ever.

Thank you for looking,
