Running XbertClassDemo.

Running XbertClassDemo.php:
1) First error: "Use of undefined constant STDIN". Of course, since it has never been defined
2) I added define('STDIN',fopen("php://stdin","r")); at the top of the PHO code (after require_once "XbertClass.php"). This handled the rror.
3) I got the following garbage-looking text on the screen:
#!/usr/bin/php -q The most interesting rule sets are for Buttermilk Pancakes, Lupus, and Macular Degeneration. Others demonstrate selected features best understood by examining the rule sets. --- Master Menu ---- 1. ButtermilkPancakes 2. Comments 3. FlowControlTest 4. Lupus 5. Macular Degeneration 6. Math 7.

Too bad.

Sorry you are having trouble. Be sure to read the documentation. It looks like you are using an operating system other than Linux, which is where Xbert was developed. Change the newline string to be CrLf and the message screen should look better. Also if you read the documentation at the top of the PHP class, you will find that I can be contacted by email.

Indeed, Bob, I run your class on Windows. But LFs have nothing to do with HTML and its appearance in the browser (where the "garbage" looking text is displayed). And then, what about undefined STDIN?
