<p class="MsoNormal">The comparison seems to work on the very latest release (as of last week) of Alice 2.3, now available for download at
<a href="http://www.alice.org">www.alice.org</a>. At least when I run it on my MacBook Pro. See the attached world and the attached screen shot…

<p class="MsoNormal"><o:p> </o:p></p>

<div>
<p class="MsoNormal">You will see that I did the comparison in two ways, using a variable with the int form of the value the user entered, and doing the comparison the the inline conversion of the value the user entered…<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Frankly, I would not have been surprised if it did not work, as comparison of real numeric values for equality is always problematic in programming, for the reasons of type alluded to in an earlier post by <span style="background:white">Claude
Gueganno.</span><o:p></o:p></p>

me know, and also let me know the OS version of Alice you are running.</span><o:p></o:p></p>
