Excuse me, but having read the article at this link, it never addresses the
question I asked. Not ONCE did you show where case sensitivity produces
errors. Please go to
http://www.tonymarston.net/php-mysql/case-sensitive-software-is-evil.html to
locate you supposedly answered my question. Then, please, copy and paste
the statement that you think answers my question.
I am reminded of what many of my students have done in the past. They
worked through a problem and gave an answer. The only thing wrong was that
it wasn't answering the question asked.

The language DID allow case. It was PHP. By the way, you keep saying that
PHP is case insensitive. That is not my experience. Run the following code
snippet:
<?php
$Junk = "this is junk";
echo "Junk = " . $Junk . "<br>";
echo "junk = " . $junk . "<br>";
?>
Clearly, PHP is case sensitive!

The direction is to use case in modern languages to make these distinctions.
Yes, it is currently by convention, but in JAVA, at least, it is a
UNIVERSALLY observed convention by ALL professional programmers.

.....and you still have not as yet detailed even a SINGLE problem caused by
case.
