Example

<h3>Insert Example</h3> 
 
<cfif IsDefined("FORM.myString")> 
    <!--- if the position is longer than the length of the string, err ---> 
    <cfif FORM.insertPosition GT Len(MyString)> 
        <cfoutput> 
        <p>This string only has #Len(MyString)# characters; therefore,  
    you cannot insert the substring         #FORM.mySubString# at position 
    #FORM.insertPosition#. 
        </cfoutput> 
    </cfif> 
<cfelse> 
    <cfoutput> 
    <p>You inserted the substring #FORM.MySubstring# into the string 
    #FORM.MyString#, resulting in the following string: 
    <br>#Insert(FORM.MySubString, FORM.myString, 
    FORM.insertposition)# 
    </cfoutput> 
</cfif>
