And I thought Lisa's issue was she didn't want to go through the mess of

widget_control,....,/APPEND
widget_control,....,SET_TEXT_TOP_LINE=...

every time she wanted to add a message line... not that packaging it in
a procedure is an unheard of trick... But the real advantage of this
method is that it works without having to trust a state variable line
count (since the widget itself is queried for the number of lines it
contains). It is therefore well suited to the creation of a single text
box for messages originating from mostly unrelated applications (sort of
like a console), without each application having to worry about what the
others are up to. And furthermore, we've got to exercise all of those
various keywords to make sure RSI isn't just fattening up the manual
with made up material!
