BUG: Errors CV1255 and EE0037 Watching Assumed Size Arrays

• Microsoft FORTRAN PowerStation for MS-DOS, version 1.0 and 1.0a

SYMPTOMS

Assumed size arrays do not display in a Watch or Locals window; instead, one of the following errors is displayed:

   CV1255 Message: no data members

   -or-

   EE0037 Error: Array subscript out of bounds

STATUS

Microsoft has confirmed this to be a problem in FORTRAN PowerStation versions 1.0 and 1.0a.

This is not a problem in FORTRAN PowerStation 32.

MORE INFORMATION

To demonstrate the problem:

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

2. Set a breakpoint on the print statement and then GO (press F5).

3. In the Watch window, type the following:

         A  <press the DOWN ARROW key>  A(1)  <press the UP ARROW key> <ENTER>
   

4. The following is displayed:

         -a
            CV1255 Message:  no data members
          a(1) = EE0037 Error: Array subscript out of bounds.
   
   

5. In the Locals window, press ENTER and the following is displayed:

         [BP+0008]-DIM        A

Sample Code

      real*4 x(10)
      x = 3.14
      call sub (x)
      end

      subroutine sub (a)
      real*4  a(*)
      a(1) = 1.2
      print*, a(1)
      end
