Well, your text widget has only one line, is that really what you
intended? If yes, skip the APPEND keyword, and you'll always see the
last string you sent to the widget. Or you can increase the YSIZE, then,
with the APPEND keyword, the new strings start at a new line.

I think IDL doesn't care about CR+LF here. To add multiple lines, just
use a STRARR, or put the single strings there one after another, with
the /append keyword.
