Creating and Manipulating Variables

This chapter describes what variables are supported by ColdFusion Express and how to create and reference ColdFusion variables. During chapter practices, you will use two of the most frequently used CFML tags, CFSET and CFOUTPUT, to create and output local variables. You will also learn how to reference CGI variables and set and reference cookies in your ColdFusion applications.
