The '''FIOLIB''' is like a strongly expanded IOLIB library, it's needed to use the programming [[:Category:C|language C]] for [[FutureOS]]. There are [[CP/M]] versions of Small-C and Windows-based cross-compilers of the C language. Use FIOLIB.C instead of IOLIB.C. The FIOLIB.C contains all needed C functions to use FutureOS system-calls.
You can take a normal C program compile it, assemble it, link the object-code with FIOLIB (and all other needed libraries), then add a header to the *.COM file with COMFU.COM.
