In particular, I'm confused what dialyzer doesn't like about line 60.<br>

Not sure what's wrong. I tried using `_` instead of `false`, but got the<br>

Dialyzer is telling you that it thinks FirstTemp will never be a binary in your program, so the case statement you have there is unnecessary. So, effectively it tells you that you can rewrite the code above to:<br>
<br>
FirstOne = FirstOneRaw,<br>
<br>
The question is why do you expect that FirstTemp may be a binary at that point?<span><font color="#888888"><br>
