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?

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.

Got it. That was my confusion.
