Example from hello-world:
main() { putchar ('Hell'); putchar ('o Wo'); putchar ('rld'); putchar ('*n'); }
Example from Wikipedia:
/* The following function will print a non-negative number, n, to the base b, where 2<=b<=10. This routine uses the fact that in the ASCII character set, the digits 0 to 9 have sequential code values. */ printn(n, b) { extrn putchar; auto a; if (a = n / b) /* assignment, not test for equality */ printn(a, b); /* recursive */ putchar(n % b + '0'); }
