Any method to do that?

No way.
But you could use a collection object with no elements

sorry, you are in VFP, not in Clipper.
Empty array is one of things that I miss in VFP.

If you are trying to tell if an array has been used yet, my VFP approach
is usually:

IF EMPTY( haha[1] )

This doesn't work, of course, if you're storing data in it which might
come back as empty, but there are other ways as well, of course, e.g.,
checking the length of the array via ALEN().

No - but in many situations you can use a cursor instead.
