Was curious, what language is the RI msoftware written in? And are there any decent assemblers about? I haven't found much medical software and would take upon a task to create some for the pre-hospital field.

RIM is written in Java, even the operating system. Applications are written as Java J2ME (Java 2 Micro Edition). If you want your application to be portable and run on all Java-powered Blackberry, Nokia, Motorola, SonyEriccson phones, you want to be compliant with MIDP 1.0 (rather than newer MIDP).

The two main big-company resources for this development are:

SUN J2ME Developers

Blackberry Developers

However, if you want the extra Blackberry API's, you may need your application to be signed by RIM. Example: Being able to force application to foreground, for displaying notifications (i.e. incoming instant messages), etc. For Blackberry-specific extensions to J2ME / MIDP1.0 you will need to visit RIM developer site.

If you need to write assembly, there are Java bytecode assembly languages available, but it's a bit of an arcane art, and probably very difficult to package in J2ME format. To the best of my knowledge, nobody has written bytecode assembler for Blackberry, but I could be wrong.

Actually the OS is not written in java just the application layer is. The OS is actually written in C++.

I could have sworn that somebody told me that at least a portion of the OS was in Java. Or was that the core OS in C++ but the RIM core apps in Java? That might be where my confusion was. Do you know if this is the case?

[eradis]

Yes you are correct. The underlying OS (i.e. radio, port etc drivers ) are all in C++ ( actually assembly too for the ARM7/9 processor), but the core RIM Apps (i.e. ribbon ) are in java.

Cool, thanks for clarrifying that 8)

Got it. That was my confusion.
