<HTML>
<HEAD>
<TITLE>Call Department</TITLE>
</HEAD>
<BODY>

<CFSET Department="Sales">

<CFSET City="Boston">

<CFSET Salary="110000"

least #Salary#.
</CFOUTPUT>
</BODY>

Development Considerations
The same development rules that apply for any programming environment apply to
ColdFusion. You should also follow the same programming conventions that you
would with any other language:
Comment your code as you go.
HTML comments use this syntax:
CFML comments add an extra dash:
File names should be all one word, begin with a letter and can contain only
letters, numbers and the underscore.
File names should not contain special characters.
