<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>
