Since all of the problems are with the read, why not
just mess up that statement.

    read(8) other, other, useful, data   !skip the first value

or even

    read(8) (other, i=1,n_skip) other, useful, data ! skip n_skip fields

It puts all of the bad stuff on one line.

PS, I thought about doing the last line as
    read(8) (other, i=1,n_skip+1), useful, data ! skip n_skip fields
but that is too obscure to even mention!
