Actually, it's a little more complicated that than. Note that TYPE('OBJECT.NAME[1]') returns 'C', not 'U'; that's true for all native properties of an object. The best way I've found is to test for element 0 as well, because while an array can't have an element 0, TYPE('OBJECT.NAME[0]') still returns 'C'. So, the following routine will return .T. if the specified property for the specified object is an array:
lparameters toObject, tcProperty
return type('toObject.' + tcProperty + '[0]') = 'U' and ;
  type('toObject.' + tcProperty + '[1]') <> 'U'
