That's right.
<blockquote TYPE=CITE>Llama
<br>triggers code in response to Windows events, passing a number of parameters

may
<br>choose to ignore certain values.
<p>For example, an onPaint event returns the area of the screen that needs
to

and
<br>simply repaint the entire window:
<p> procedure Paint( integer x1, integer y1, integer x2, integer
y2 )
<br> ... repaint the window ...
<br> end procedure
<p>Since the "without warning" option is not selected, Euphoria helpfully
<br>issues warnings about each of these parameters:</blockquote>
<blockquote TYPE=CITE> warning: parameter x1 in Paint() is
not used
<br> warning: parameter y1 in Paint() is not used
<br> warning: parameter x2 in Paint() is not used
<br> warning: parameter y2 in Paint() is not used
<br> </blockquote>
So if I just put "without warning" in my Llama file it will stop the warnings???
<blockquote TYPE=CITE>
<br>Multiply this by a handful of similar event handlers, and you have
a
<br>screenful of warnings.</blockquote>
More than a screenful!
<blockquote TYPE=CITE>I've left them in because (1) in some cases, they
are
<br>actually useful warnings,</blockquote>
It's Possible that they are useful..
<blockquote TYPE=CITE>and (2) it reminds people that Llama is still
<br>alpha software.
<br> </blockquote>
Definitely alpha software!
<blockquote TYPE=CITE>
<br>I hope this helps!
