Volume III - “List Variable Operations” Chapters

Volume III
Summary of Chapters

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

Chapter 1- Debugging List Variables	The Omnis Studio Debugger offers us some very useful features for examining and manipulating list variables. This is essential knowledge for a developer.
Chapter 2- Adding and Removing List Lines	Volume II described the basic commands and methods for adding, updating and removing list lines, but did not give any examples. This chapter examines these processes in much more detail.
Chapter 3- Searching and Scanning	An important feature of a list variable is our ability to select lines or set the current line based on search criteria. There are also a number of techniques we might use for processing the lines of a list or the records associated with them by stepping through those lines.
Chapter 4- Sorting and Shuffling	The order of the lines within a list variable can be an important factor in the efficiency of various list-based operations as well as making the display of these lines more meaningful for the user. We also have the power to randomize those lines for comparison testing.
Chapter 5- Cloning and Combining	List variables can be copied and combined in many ways. It is important to understand how to manage these processes.
Chapter 6- Adding and Removing Columns	Most list manipulation processes are line-based. But there are a few column-based manipulations we can perform as well. This chapter demonstrates how useful column operations can be.
Chapter 7- Importing and Exporting	List variables are a principal means of importing and exporting data between Omnis Studio applications and between omnis Studio and other programs. Omnis Studio gives us a number of advantages over previous generations of the product.
