I do still use them, but it feels nearly as unsatisfactory as using goto. For example, in constructions such as this: a[++n] = 0; b[n] = 0; c[n] = 0; You have to be careful to increment n just once. If you start with a[++n]=0 and decide you need b[] updated too, you can't just copy that line and replace a with b; you have to fix that ++n. And if you later decide you don't need a[] updated after all, that ++n now has to be inherited by the next line. Or if there is only a[], but you still need n incremented, now you need ++n. Or you want to assign c[n[ first. etc. It's all a lot less troublesome just writing: ++n; // apt comment that is out of place next to a[++n] a[n] = 0; b[n] = 0; c[n] = 0; The assignments are more balanced too. -- Bartc
