BUG: Expicit-Shape Array Elements Not Displayed in Debugger

• Microsoft Fortran PowerStation for Windows 95 and Windows NT, version 4.0

SYMPTOMS

When you debug an explicit-shape character array in a subroutine and view the expanded array elements in the locals, watch, or quickwatch window, only the first two array elements contain values; the rest are blank.

RESOLUTION

You can view the full contents of the array in the memory window. For more information on using the memory window, please see the topic "Using the Memory Window" in the Microsoft Fortran PowerStation version 4.0 Books Online help facility.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

Build the following sample code in Developer Studio. Begin debugging the program by clicking Debug on the Build menu, and then click Step Into. Step into the subroutine sub(), and go to the return statement. In either the watch or quick watch window, type the explicit-shape array variable name "I" and then expand the array elements by clicking the nesting symbol (+).

NOTE: All the array elements contain blank spaces except for the first two.

Sample Code

C Compile options needed: /Zi

      CHARACTER(LEN = 10),DIMENSION(8)::H
      H = 'AAAAAAAAAA'
      CALL SUB(H)
      WRITE(*,*)'Done debugging...'
      END

      SUBROUTINE SUB(I)
      CHARACTER(LEN = *),DIMENSION(8)::I
      I = 'BBBBBBBBBB'
      RETURN
      END SUBROUTINE SUB
