Ok this is basically a project that I want to be like TIGCC but for the 83 series family. I know C code but I need another person that knows C and someone that knows TI 83+ Assembly because I need to know the Assembly commands that the C commands will compile too. If you are willing to help please respond.

I thought you couldnt do C for 83+ since it was too slow

C isn't an OOP language. The only existing C->z80 compilers run as slow as BASIC programs. You could ask mbruno on irc. He is found in #tcpa on the efnet server. He has been working on a C->z80 compiler.

I mean the ones on PC produce code that runs as slowly as BASIC.

Well, perhaps people are looking at the problem wrong?  Maybe these z80 ASM experts working on the C->ASM compilers should try a totally radical technique in writing compilers.  Considering z80 is 8-bit/psuedo 16-bit, it's probably difficult to include all the features of (32-bit) C.  After working with TIGCC for awhile and comparing it to the little z80 knowledge I have, I've noticed that 32-bit programming seems considerably different from 8-bit/16-bit.

My suggestion is perhaps to write a C->ASM compiler, but also create an ASM optimizing program (kind of like source coder? am I right?).  I don't know if it's possible though.  Actually, ASM optimizing is somthing that could be very helpful for the community because it takes a lot of experience before one can write efficient and optimized ASM code that could power the engine of say, an FPS.
