Indeed they weren't, and that's how we know that 1-based indexing doesn't
require any overhead given a reasonably good compiler. If you'd gone to people
writing big CFD simulations in 1975 and told them that by using a version of FORTRAN which
had 0-based arrays they could save any significant runtime at all then they would have
changed to it without a thought. But they didn't.
