[[Category:Programming]][[Category:FutureOS]]With The '''FIOLIB''' is needed to use the programming language C for [[FutureOS]] it also possible to use C as a programming language. There is a are CP/M version versions of Small-C and also Windows-based cross-compilers of the C language. You have to use Use FIOLIB.C instead of IOLIB.C. becase The FIOLIB.C contains all needed C functions to use FutureOS system-calls.
You can use take a normal C program compile it, assemble it, link the object-code with FIOLIB (an and all other needed libraries) and , then add a header to the *.COM file with COMFU.COM. To start such an C-program under FutureOS you have to start the RUNC-environmentpreviously. RUNC expands the features of FIOLIB. With RUNC it is possible to store functions in E-expansion RAM, leaving more main memory free for C applications.
