Netscape: Untitled File Edit View Go Communicator Location: Enter some text: You entered: Jack & Jill

What happened was:

1. We submitted the form, with the <INPUT> tag txt set to Jack & Jill . Vortex automatically copies any form data - GET as well as POST - to Vortex variables of the same name. So our $txt variable is set to Jack & Jill .

2. main prints the form - pre-filled with our submitted text because $txt is set.

3. The main function ends, and the script ends.

HTML escapement

An important feature to note here is that we entered data that needs HTML escapement when printed - the ampersand (& ). Vortex automatically HTML escapes variables when they're printed, so we don't need to worry about it. (We can verify this by looking at the HTML source in our browser - the & is shown as &amp; .)
