Description
A conditional loop iterates over a set of instructions as long as a condition is True. To use this type of loop correctly, the instructions must change the condition every time the loop iterates, until the condition is False. Conditional loops are known as WHILE loops, as in, "loop WHILE this condition is true."

<cfset CountVar = 0>
<!--- Loop until CountVar = 5. --->
<cfloop condition = "CountVar LESS THAN 5">
<cfset CountVar = CountVar + 1>
The loop index is <cfoutput>#CountVar#</cfoutput>.<br>
</cfloop>The output of this loop is as follows:
The loop index is 1.
The loop index is 2.
The loop index is 3.
The loop index is 4.
