Re: [9fans] [OFF-TOPIC] It is true that is impossible write in binary code, the lowest level of programming that you can write is in hexadecimal code?

[David Hoskin <root@davidrhoskin.com>]

It's certainly possible!

If your machine doesn't have those cool front panel toggle switches,
just use this simple compiler:

#include <u.h>
#include <libc.h>

void
main(void)
{
	char buf[8];
	int i;
	char c;

	while(read(0, buf, 8) == 8){
		c = 0;
		for(i = 0; i < 8; ++i){
			switch(buf[i]){
			case '0':
				break;
			case '1':
				c |= 1 << (7 - i);
				break;
			default:
				exits("two");
			}
		}
		write(1, &c, 1);
	}

	exits("");
}

Octal is popular for these things.
