ArrayInsertAt (array, position, value)
Inserts a value into an array at a specified position and returns true if successful. Array elements whose indexes are greater than the new position are incremented by one. The array length increases by one.
<cfset zipcode = ArrayNew(1)> <cfset zipcode = 80202> <cfset zipcode = 80203> <cfset zipcode = 80205> <cfset ArrayInsertAt (zipcode, 3, 80204)> <cfoutput> Array index position 3 is now: #zipcode# </cfoutput>
