Thanks Fabrice and Aditya!

With three completely different approaches, I learned three times more than= I was expecting. This has been a great help. I will probably use the frame= dtext method, but I learned something from each.

Differen= t problems require different amounts of space, so this should be an argumen= t or key-value.
