About rich text
Rich text format (RTF) is a standard for specifying formatting
instructions and document content in a single ASCII document. An
editor that supports rich text format interprets the formatting
instructions and displays the text with formatting. If you look
at rich text in a plain ASCII editor, you see complex instructions
that are not very readable. The actual text of the document is buried
amid all the formatting:

The same sample displayed without the commands looks like
this:

Elements of rich text
Rich text in PowerBuilder can have:
- Margins and tab settings for each paragraph
- Character formatting such as italic, bold, underline,
or superscripts for each character - Named input fields associated with database columns
or other data - Bitmaps
- A header and footer for the document
The user can use toolbars, editing keys, and a popup menu
to specify formatting. A print preview lets users view a reduced
image of the document to see how it fits on the page.

style. You can also add a RichTextEdit control to a window or visual
user object.
