Array? Why would you use array?

>
>I have a code where I declare a local array then I GATHER into this array and then SCATTER; nothing special there. But then at the end of this function I have:
>RELEASE aArrayName
>
>Since the array is local, do I really need the RELEASE? This release has been in the code for many many years and of course I don't remember why I put the there.
>Any suggestions? TIA.
