Arrays of entities

Ack! Seems that these two things don't go together. Apparently I can;t have an array of type and use a function to populate it.

Type actor
  Field x
  Field y
  Field z
End Type

Dim actors.actor(10)

For n=0 to 9
  actors.actor(n)=test_func()
next

Function test_func()
  entity.actor=New actor
  entity\x = rnd(-10,10)
  entity\y = rnd(-10,10)
  entity\z = rnd(-10,10)
  Return entity
End Function

or alternatively

Type actor
  Field x
  Field y
  Field z
End Type

Dim actors.actor(10)

For n=0 to 9
  actors.actor(n)=New actor
next

For n=0 to 9
  actors.actor(n)=test_func()
next

Function test_func()
  entity.actor=New actor
  entity\x = rnd(-10,10)
  entity\y = rnd(-10,10)
  entity\z = rnd(-10,10)
  Return entity
End Function

and various variations. Is this a doomed mission or can you educated types bestow your wisdom upon me?
