Debugger Message EE0029 Cannot Access User Memory

ID: Q106724

The information in this article applies to:

Microsoft FORTRAN PowerStation for MS-DOS, versions 1.0, 1.0a

SUMMARY

The PowerStation debugger displays the following message

EE0029 Error: Cannot access user memory

in the Watch window when a formal argument of a subroutine or function cannot be displayed. A formal argument can be viewed only if the current point of execution is within the subprogram accepting the formal argument. Once the first line of the subprogram has been executed, the formal arguments display correctly in the Watch window.

This problem does not occur with FORTRAN PowerStation 32.

MORE INFORMATION

The EE0029 error can be generated by following these steps:

Build the sample code with the project in debug mode.

Set a breakpoint on the line with "a = c+1.2" and GO (press F5).

Set a watch on a and c. The value for c will be:

EE0029 Error: Cannot access user memory.

Single step once and the value of c will now be displayed.

Sample Code


Compile options required: /Zi
      real*4 b
      b = 2.
      call sub (b)
      end

      subroutine sub (c)
      integer*4   a
      real*4      c
      a = c+1.2
      print*, a
      return
      end
