Penda,

It is correct that properties cannot be passed by reference, they can by value but that doesn't help your array situation.

You can get the same effect by passing the object itself along with the name of the array property. Assume an object with an array property named MyArray. You can do this;

* some code inside the object with the array property
SomeotherObject.SomeMethod(THIS, "MyArray")

Now in the other object you would;

LParameters toObject, tcArrayName
WITH toObject
   FOR LnCnt = 1 TO ALEN(.&tcArrayName,1)
      .&tcArrayName(lnCnt) = "Blah"
   ENDFOR   
ENDWITH
RETURN

This works because you can pass objects around.
