Yes, it does work, but probably not like most folks would like. Try the following:
FUNCTION ArrayTest
  LPARAMETER ta_foo

  EXTERNAL ARRAY ta_foo
  DIMENSION ta_foo[2]
  ta_foo[1] = "A"
  ta_foo[2] = "B"
  RETURN ta_foo
ENDFUNC

DIMENSION a_foo[1]
a_foo = NULL
a_foo = ArrayTest(@a_foo)
DISPLAY MEMORY LIKE a_foo
You'll see that the array is re-dimensioned but the values in both elements are the same. I also tried this with numbers.
