Unconstrained arrays

[ucivax!gateway@ucbvax.Berkeley.EDU (Kenneth Anderson)]

Hello,

  I have declared the following type (DynamicString is an imported type)

        type Str_Array is array (Natural range <>) of DynamicString;

Later when I try to declare objects of this type, the compiler likes this


   Viewers : str_array(1 .. 6) := (Create("Airspeed_Guage"),
                                   Create("Altimeter_Guage"),
                                   Create("Compass_Guage"),
                                   Create("Horizon_Guage"),
                                   Create("ROC_Guage"),
                                   Create("Turn_Guage"));

but it does not like this

   Viewers : str_array(1 .. 1) := (Create("text_artist"));

Here is the error message generated by the SunAda 1.1 compiler


--### A:error: RM 8.3: no visible identifier is of type str_array


If I change the above declaration to

   Viewers : str_array(1 .. 2) := (Create("text_artist"),
                                   Create("ignore"));

The compiler is happy again.

  Can someone help me out on this?  Why can't I declare AND initialize
an array of only one element?

Any help would be appreciated,

Thanks in advance,
