or ascii files, Gri will proceed to a new line
after it has read the items requested; it skips any words appearing on
the data line after the last object of interest.  Thus

columns that might be present.  But for binary files, Gri has no way of
knowing how to "skip" to the next line (see `<font color="#82140F"><code>skip</code></font>' command), so you
will have to flesh out the `<font color="#
