int tmp;
for (tmp = 0; tmp<=12345; tmp++)
if (!(tmp%1000)) printf("%d mod 1000 is %d\n", tmp, tmp%1000);

/*
results in (vice x64)
0 mod 1000 is 0
232 mod 1000 is 0
1000 mod 1000 is 0
Interesting:
1000 = $3E8
232 = $E8
So testing with 999 gives:
0 mod 999 is 0
231 mod 999 is 0
999 mod 999 is 0
This seems to be systematic.
