This method displays a screen defined as a record format in a Rich Display File, waits for the user to respond, and reads the response. It is equivalent to issuing a display.screen.write() immediately followed by a display.screen.read().
- Data structure (optional) - A Profound.js data structure reference. If specified and not null, the screen is populated with the values from the data structure and the response is repopulated back into the data structure. If not specified or specified as null, global fields are used to send and receive values to and from the screen. If the data structure is not qualified, you must wrap the parameter with the pjs.ds() API.
