Programming

[p]This section documents the symbols, tags, expressions, and data types which allow programming logic to be specified within Lasso pages. This section contains the following chapters. [/p]

• Chapter 14: Programming Fundamentals introduces basic concepts of Lasso programming such as how to output results, how to store and retrieve variables, and how to interact with HTML forms and URLs.
• Chapter 15: Variables introduces concept of variables including global variables, local variables, and page variables.
• Chapter 16: Conditional Logic introduces the [code][If][/code], [code][Loop][/code], and[code] [While][/code] tags and demonstrates how they can be used for flow control.
• Chapter 17: Encoding explains how strings are encoded in Lasso for output to many different languages and the tags and keywords that can be used to control that output.
• Chapter 18: Sessions explains how to create server-side variables that maintain their value from page to page while a visitor traverses a Web site.
• Chapter 19: Error Control introduces Lasso’s error reporting mechanism and explains how custom error tags can be created and what tags can be used to handle errors which occur while processing a Lasso page.
