Depends on what you are doing here. If you are trying
to print it, you can do this:

   Print, "Hello" + String(10b) + "There"

If you are putting it on a title of a plot, or
writing it into a graphics window, you can do this:

   XYOutS, 0.5, 0.5, Align=0.5, /Normal, "Hello!CThere"

Not sure what you are asking for with "lat-lon box",
but perhaps it is the LIMIT keyword. (?)
