Chapter 22. Dynamic Functions > Using Dynamic Functions

Using Dynamic Functions

ColdFusion features three dynamic functions, which are designed to facilitate the run-time creation and evaluation of expressions (and thus are dynamic). Using a dynamic expression to access or assign variables, it is possible to replace multiple lines of <cfif> and <cfset> statements with a single line of code. The dynamic functions are IIf(), DE(), and Evaluate(). All of these functions will be covered in the next few pages.

→ Refer to Chapter 2, “Working with Variables and Expressions,” and Chapter 3, “Conditional Processing,” for the CFML tag equivalents of the <cfscript> discussed here.
