If you've got some VB experience and you have a reasonable understanding of functions and subroutines, you may have the tollerance and experience to survive the developers guide for Prontoscript.

I believe that there is a copy in the files area of this web site as well. The nice part about using the dev guide is that the appendix contains descriptions and definitions for all the methods and properties that are available in Prontoscript (aka javascript).

The only annoying thing you are going to run into is that Prontoscript is a run time language with no compiler. Thus you don't have an integrated development environment (IDE) that will spot typing and syntax errors. If I've captured your interest: Get a free copy of VB.net 2008 (express edition). You can create jscript files and use the intellisense features to help with the syntax checking. Just remember that Prontoscript is a partial implementation of what jscript offers.
