I tried this: #include unsigned char Receiver = 0; int main(void) { Receiver = 0x00; printf( "Receiver -=>%c\n", Receiver ); return(0); } compiled it with: gcc -W -Wall -ansi -pedantic -Wbad-function-cast -Wcast-align \ -Wcast-qual -Wchar-subscripts -Winline \ -Wmissing-prototypes -Wnested-externs -Wpointer-arith \ -Wredundant-decls -Wshadow -Wstrict-prototypes zz.c -o zz and no warnings.... -Mike
