FIX: Debugger Error EE0044 for Arrays If Lower Bound Not 1

• Microsoft FORTRAN PowerStation for MS-DOS, version 1.0

SYMPTOMS

The Locals and the Watch windows show error EE0044 instead of the values in an array declared with lower bounds other than 1.

RESOLUTION

If possible, EQUIVALENCE the array with lower bounds other than 1 with a same-sized array with lower bounds of 1. Then view the elements in the array with the lower bounds of 1.

STATUS

Microsoft has confirmed this to be a problem in FORTRAN PowerStation version 1.0 for MS-DOS. This problem has been resolved with FORTRAN PowerStation maintenance release version 1.0a for MS-DOS.

MORE INFORMATION

FORTRAN PowerStation version 1.0 can be differentiated from the maintenance release version 1.0a by invoking the linker. Typing link32 | more from \F32\BIN directory will show version 2.8 for FORTRAN PowerStation version 1.0, and it will show version 1.0f for the maintenance release version 1.0a.

Neither the Locals nor the Watch window can display the values in an array declared with lower bounds other than 1. For example a(10) and b(1:20) work but c(-1:5), d(0:34), and e(4:8) do not work.

Regardless of the actual declared lower bound, if it is not 1, then the debugger will attempt to display the array as if the lower bound were 0 (zero). For example, with A declared as A(2:4), the debugger will display five elements: A(0) to A(4).

To demonstrate the problems:

1. Build the sample code with the project in debug mode.



2. Step to the print statement. At this point all three elements of ARR are 100.3.



3. In the Watch window, enter ARR and ARR(2).



4. Click "+ARR = {...}" to display the full array. At this point the Watch window will show:

   
         -ARR
            (ARR)(0) = EE0044 Error: Type error.
            (ARR)(1) = EE0044 Error: Type error.
            (ARR)(2) = EE0044 Error: Type error.
            (ARR)(3) = EE0044 Error: Type error.
            (ARR)(4) = EE0044 Error: Type error.
          ARR(2) = EE0044 Error: Type error. 




5. Open the Locals window. ARR will be displayed the same way.

Sample Code

C Project options needed: Debug mode

      real arr(2:4)
      arr = 100.3
      print*, arr(2)
      end
