The above syntax you had in your email is exactly what we do here. Of course, as
most of you know, we don't use the markup tags we strictly do Java code inside <%
... %>. I find it interesting that as most of you try to deal with using markup
tags, you inevitably run into commands/tags that are supplied. There is a reason
why languages like Perl, C, and Java have so many commands, and that's because
inevitably you are going to need to use them. As someone mentioned, what about
the Case command? What about for next loops? Eventually you will simply redevelop
the language, but it won't be a common language like Java it will be something
original and new to most developers. One big advantage of JSP is that you can
hire an experienced Java developer, regardless if he has ever heard of JSP.
