Volume II - “List Variable Definitions” Chapters

Here is a brief summary of the chapters in this second volume of the OmniScience Omnis Reference Library.

Chapter 1- List Terms and Concepts	The first concern in any technical discussion should be the definition of terms so that the clearest communication can be achieved involving the concepts those terms represent. To this end, let’s pin down a few important concepts regarding list variables with specific words or phrases so we can work with them.
Chapter 2- Preparing for Content	A list variable is just a shell. We can't do much with it until we prepare it for content by specifying the variables it will contain. Then again, there are still some uses we can make of an unprepared shell...
Chapter 3- Adding Content	We generally need to provide a list variable with collections of values. There are many ways to do this. Here are the basics.
Chapter 4- Addressing Existing Content	Once a list variable contains some values, we will need to access some or all of this content. There are many ways Omnis Studio allows us to query and update specific cells within a list variable as well as to derive aggregate information (counts, totals, etc.) from the contents of a list variable.
Chapter 5- List Line States	There are two independent states that a line of a list variable can express. There are a number of ways we can manipulate and use these states in our applications.
Chapter 6- List Notation	Omnis Studio allows us to access many aspects of a list variable through Notation. There are also a number of built-in methods for a list variable or its component parts that require notational techniques for their execution.
