DEVELOPING COLDFUSION 9 APPLICATIONS
The CFML Programming Language
<cfset myArray = ArrayNew(1)>
<!--- Use ArraySet to initialize the first ten elements to 123 --->
<cfset ArraySet(myArray, 1, 10, 123)>
<cfset myArray[4] = "kumquats">
<cfset foundit = False>
<cfset i = 0>
<cfloop condition = "(NOT foundit) AND (i LT ArrayLen(myArray))">
<cfset i = i + 1>
<cfif myArray[i] IS "kumquats">
<cfset foundit = True>
</cfif>
</cfloop>
<cfoutput>
i is #i#<br>
foundit is #foundit#<br>
</cfoutput>
Note: You can get an infinite conditional loop if you do not force an end condition. In this example, the loop is infinite if
you omit the

However, get in the habit of consistently using the same case rules in your programs; for example:
cfsEt.
• Develop consistent rules for case use, and stick to them. If you use lowercase characters for some tag names, use
them for all tag names.
• Always use the same case for a variable. For example, do not use both myvariable and MyVariable to represent the
same variable on a page.
Follow these rules to prevent errors on application pages where you use both CFML and case-sensitive languages,
