If I understand correctly, you would like the format line to be
optional, but if specified to be preceded by the work "col". As an
option, the second format statement above might also be used (col "ll").
I'll have to look carefully at my code to see how to make such a change.
Currently, I'm checking the row number to see if it should be a format
description or not. However, I don't see why your suggestion could not
be employed in principle.

This might be a LOT more work. I specifically chose to minimize the
impact of my code on James' work for two reasons:
My C++ is somewhere past novice, but not yet at an intermediate
stage. So I thought 'tacking' my code on would ensure that I
didn't muck up his.
I didn't understand his code, but I must admit that I didn't
spend a lot of time studying it. I chose to get the job done in
a manner that I knew would work, as I had some experience with
(f)lex in previous projects.
If you insist, then I'll spend some time on James' code to see how it
might be done. Note that I'm away for a week, and MAY (if I'm lucky) be
re-integrated into the workforce upon my return. If that doesn't
happen, then I'll certainly have a look.
