Analog = digital?

A friend of mine said he thought he remembered that someone had once proven
that digital computers were theoretically equivalent to analog computers --
that is, that they could compute anything that an analog computer could
compute.

But somebody just said, "No, there is no such proof."

I thought I'd ask here whether anybody knew either way.

Thanks,

John
