It interprets 04 as (0*10 * 10). >It looks like they're compiled from the same sources even --?? No, sh uses its own limited formatting routine doformat(). I think the sources are shared between csh(1) and printf(1), but then I thought that they were shared with sh(1) before I looked at them :-). Perhaps everything should use vfprintf() and fwopen(). There's little chance that everything would agree about obscure flags or floating point otherwise. sh doesn't understand floating point formats at all... Bruce
