Classical sequential files, however, were simply random-access files
such that seeking to line n was just a matter of seeking to byte
n * MAXCHARSLINE. The last time I actually used such a thing was
on an early Tandem system when I was implementing the Software Tools.
Editable source used a different format, so I set things up so that
the Tools could either read source format or sequential format and
then wrote sequential format.

At the end of the Metatarsal Age, the dinosaurs abruptly vanished.
The theory that a single catastrophic event may have been responsible
has been strengthened by the recent discovery of a worldwide layer of
whipped cream marking the Creosote-Tutelary boundary. --Science Made Stupid
