The Z80 is going to have many compiler choices, but few that target C - why would they ?. When you go through another hop like this, you loose important debug coupling to your source code, and it's not clear what you gain. The Z80 is also not likely to attract truckloads of active development ;) An alternative would be to find an abandon-source form of the language you want, and create a C-ASM output format - that should give 'other language in', and give other-C-linking, which I am guessing is why you need C. In the PLD realm, it is now common to see Verilog/VHDL, as low-level 'assembler' languages inside the tool chains. If you do not need other-C-linking, just take the language native Z80 output ? -jg

I'm not sure what you are _really_ trying to find. C++ used to be translated to c with something called cfront. Up until version 4, when growing exception handling requirements finally forced a transition to true c++ compilation to object code. cfront is largely dead, now. But that doesn't mean it wouldn't still be an option. It did a great job for what it did. Of course, I have no way to know if it meets your needs. There's p2c for a Pascal. Klaus Bothe wrote these two papers, for example: "Rules for the Transformation from Pascal to C," 1987 "A portable high-speed PASCAL to C Translator," 1989 I remember something called f2c, as well. There was also RATFOR, back in my college school days, which translated a "nicer" version "rational FORTRAN" to FORTRAN II code. It was very easy to implement on your own and worked well. And GNU compiler front ends exist, as well. Even for ADA, I believe. Could you talk about _exactly_ what you feel you need here, and why? Jon

I think we've got a pretty good clue that it won't meet his needs: 1KB RAM and 32KB of ROM. :) -- Grant Edwards grante Yow!
