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 -

-
A header and footer for the document
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.
