I just bought "RTF Pocket Guide" with the intention of learning more about RTF.

Thanks for taking the time to give me your ideas on this. I see now that I am at
least on the right track.
There are probably many ways to go about manipulating text within the RichEdit
control. I have much more than just RTF to learn about I'm sure.
Looks like I will also need to learn more about riched20.dll and how to use it
from within Euphoria.
(hopefully I'll get the hang of using this forum along the way...)
This should be interesting and fun too:)
