What You Must Know About ColdFusion Flow-Controls - Call a halt and end
(Page 6 of 6 )

The <cfabort> tag

As soon as <cfabort> is reached, the process aborts, and only what happened up to that point is retained. The syntax is:

Example 12

The code in the previous example is modified again to demonstrate the <cfabort> tag.

<cfset vol=5>
<cfloop condition="#vol# lt 10">
<cfoutput>Count is  #vol#</cfoutput><br/>
<cfset #vol#=#vol#+1>

The displayed output when this code runs is as follows:

Count is 5


The flow-control tags discussed in this tutorial are very essential. It helps to practice with them, creating scenarios that you might have come upon in your learning experiences. In addition to the tags, the script can also be used as shown in a majority of the cases. The script is the equivalent of the tags; however, there are certain keywords used in the script for which there are no tag equivalents. These snippets have been tested on the MX 6.1 server by placing the files in the virtual directory. A good understanding of the previous tutorials will be required to work with this tutorial.
