.
When
embellished
is set to

, all other character codes are returned along with the message.
When

is set to

, only the message and the

character code is returned. For
information on the embedded character codes, see display.settext() (on page 11-141).
The display is not switched to the user screen (the screen set using
display.settext()
). Text is
read from the active screen.
