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