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 formatted content. 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 obscured by the formatting
instructions:

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 -

The user can use toolbars, editing keys, and a pop-up menu to
specify formatting. A print preview lets users view a reduced image of
the document to see how it fits on the page.
