Scripting in Frontier
This tutorial introduces the scripting component of Frontier. It will get you writing scripts in Frontier's language, UserTalk, so that you can put Frontier's power to work for you, solving problems you want to solve, doing jobs you want done.
This tutorial is a hands-on exercise.
First we'll write and refine some simple scripts, for practice. Then, we'll write a userful, powerful Frontier script from the ground up: we'll start by stating what we want to accomplish on the computer, we'll plan how to do it, and we'll put the plan into action with Frontier.
When we're done we'll have a bells-and-whistles Frontier script that you can use to impress folks with your scripting prowess, and that also does something darned useful if you happen to be a Web site manager.
At that point, you'll know enough about UserTalk, and enough about how to find out more, to be able to go on independently to develop scripts of your own.
The scripts in this tutorial are all cross-platform. They work equally well on Windows and Macintosh.
