If so, why? It's certainly not necessary in Java. It is necessary in C, but C is a very old language designed to fit in systems with 32K of memory where the entire program couldn't be stuffed into memory first. I'll fix the closing parenthesis. I'm surprised that worked at all. That makes this work with Safari now too. Is it really necessary to declare a function before you call it? If so, why? It’s certainly not necessary in Java.

The same goes for the function <code>make_button()</code>. I haven't tried this plugin out but it looks good! Regards, johnbillion Elliotte,
