	In C, you can define macros.

	Your statement can as well becomes:

	#define or ||
	#define and &
	#define eof _EOF
	#define error _ERR
	#define flag fp->_flag
	#define read _READ

	x = ( ( flag and read ) == 0 ) or ( flag and ( eof and error ) ) <> 0 );

	For a complicated statement, this is just as clean and as readable as
	Pascal, Modular 2, Ada will do it.
