Welcome to the Scripting Run-Time Library Reference

These handy blocks of information will help you explore the many different parts of the Scripting Run-Time Library.

You'll find all the parts of the Scripting Run-Time Library listed alphabetically under the Alphabetic Keyword List. But if you want to examine just one category, say, objects, each language category has its own, more compact section.

How's it work? Click on one of the headings to the left to display a list of items contained in that category. From this list, select the topic that you want to view. Once you've opened that topic, you can easily link to other related sections.

So, go ahead and take a look! Study some statements, mull over the methods, or figure out a few functions. You'll see just how versatile the Scripting Run-Time Library can be!
