Hello,

I'm developing a new application for the Palm OS, and I'm considering using OrbForms and PocketC for the bulk of the application development. My question is, if my application requires me to use more advanced functions in the Palm libraries (beyond those supposed by PocketC), is it possible to generate native C code from the code created in PocketC? For example, once I've created my GUI and corresponding functions, I may need to do some low-level coding to send files back and forth to a PC via a bluetooth.

Hopefully I worded my question right. If you need more information or a better explanation, please let me know.

Thanks,

Jeff

What you are trying to do can be done by creating native add-ins. A native add-in is a function/object exposed to OrbC that is implemented in native code.

Thanks, that's what I needed to know. So far I love the PocketC product. It's allowed me to make some progress on a project that's been handicapped by my stale C skills, and lack of time to muck with all the events and states in the Palm OS.

One question on performance: Most of my app will not be resource intensive, but just as a point of comparison, once I have the final product compiled into a .prc file, assuming this is a mostly form-driven application, what performance difference should I expect when compared to a native Palm C app?

Performance is not a simple measure. If your application really is mostly form-driven, you will not see any significant difference between an interpreted program (Pocket C, OrbForms, PocketC Architect) and a purely native program. Most of the time is spent in the Palm OS waiting for user interaction. If you're doing database access the rest of the time, you also will not see any significant difference since most of the time is spent in the Palm OS's database routines copying stuff around or looking for stuff. The main place where you'll see a difference is in numeric calculations or numeric searches. Most of the character by character string manipulation or searching is speeded up by the run-time doing the character by character work on strings internally. If you're doing something like pattern matching, you'll need a native add-in to do that efficiently, but most other string stuff is relatively fast.
