Hi, all. I want to make FAT code resource which can be called from FB using CALL statement. Can I do that? If anybody had done, and if any source codes available, let me know. I use FB 2 and CodeWarrior Pro 3 and 4. The code I wrote in FB runs fast more than enough, but, I think if I wrote it in C, it runs more faster. Anyway, can I know that the CPU is PowerPC or not? If so, I use FB for 68k and call coderesource for PPC. I know how to build 68k only/PPC only code resource. i.e. LONG IF cpu_ppc resH& = GET RESOURCE (_"CODE",_myResID) resH& = FN HLOCK (resH&) RESIGTER (A0) = [resH&] ` jsr (A0) CALL RELEASERESOURCE (resH&) ' or CALL "CODE",_myResID XELSE FN myFunc END IF Thanks.
