    RTF made easy for RichEdit

    Below is my wrapper for making RTF commands easier to understand and use in a RichEdit.

    According to http://www.biblioscape.com/rtf15_spec.htm#Heading52
    there is a TON of stuff to the RTF and I am only scratching the surface, but this will give users a leg up on learning RTF.

    Discussion on the concept can be found at http://www.powerbasic.com/support/pb...ad.php?t=39482

    The RichEdit window shows the resulting code, and the textbox shows how the code would appear if it were all text (with RTF commands)

    Now for the fun stuff

    StringAsRichTextFormat.inc
    Code:
