Converts character to upper case.

This is a small example program, that shows how to use the '''FIOLIB''':
<pre>
/*
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.
