Anyone?

I am looking for a way to have multiple colors on a single subfile field.  I 
have a 90 character field that I need to color various sections of it 
differently.  In this application, I cannot afford to break the field up, to 
add a blank attribute field to the beginning of each color section.  I need 
(want) to assign each section of the field a different color, without breaking 
it up, so one color buts up against the next in the field.  I believe I saw 
this method a few years ago but have not been able to track it down again.

Does anyone know of this method and would like to share it?

Thanks!

Don
