With [[Category:C]][[Category:Extended RAM Software]][[Category:FutureOS]][[Category:Programming]][[Category:Programming software]]The '''FIOLIB''' is like a strongly expanded IOLIB library, it's needed to use the programming [[:Category:C|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.

Converts character to upper case.

This is a small example program, that shows how to use the '''FIOLIB''':

/*
FTEST.C - 03.02.2005 - 174 Lines
FTEST.C is to show how to write programs for
the Amstrad CPC under FutureOS in Small-C.
Compile (under CP/M):
A>cc -M ftest
A>zmac ftest=ftest
A>zlink ftest=fiolib,ftest,printf1
A>comfu ftest
COMFU.COM converts FTEST.COM to FTEST.SMC
by appending an 128 byte FutureOS header.
Start (under FutureOS):
RUN the RUNC.64K file, then
RUN any .SMC application, like FTEST.SMC (this here)
