2. Concatenates the list of values into a single prompt string. The total length of this string, plus the users response, cannot exceed 80 characters.

3. Displays the resulting string on the Prompt line of the current form (or in the Line mode overlay, if it currently covers the Application window)..

5. Reads whatever value was entered until the user presses RETURN, and then stores this value in response variable.

The prompt string remains visible until the user enters a response.
