Could maybe have done it all with macros, but I wanted to write my own itoa function. Plus I feel like using the preprocessor for its looping directives takes the challenge out of the problem. To extend to larger numbers, all you have to do is increase the size of the buffer and modify START_BOTTLES.
<lang>// Compiles with `gcc -nostdlib`
#define SYS_EXIT $60

counter:
.quad START_BOTTLES

.byte 'x
