  OFFICE MEMO          overstriking in text window             Date: 10/18/90
has anyone had luck in overstriking characters in a text or Fred window. 
basically, to display phonetic information beyond the special characters
already available in a font, I need to be able to overlay macron and various
accent characters on a preceding character.   any clues/code?

thanks
