You can prepare rich text in any word processor that can save or export rich text format.
Although many word processors support some kinds of fields, the fields are usually incompatible with other rich text interpreters. If you want to specify input fields for a PowerBuilder application, you will have to insert them using the PowerBuilder RichTextEdit control.
Since rich text is represented by ASCII characters, you can also store rich text in a string database column or string variable. You can retrieve rich text from a string database column and use the PasteRTF function to display the text with formatting in a RichTextEdit control.
