BUG: Compiler Fails to Detect Illegal Use of DO Variable

Last reviewed: February 29, 1996
Article ID: Q147747

The information in this article applies to:

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

SYMPTOMS

The compiler fails to detect an illegal redefinition of a DO variable by an implied DO loop inside a normal DO statement.

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

Sample Code to Illustrate Problem

C Compile options needed: none

      integer i, j, arr(2,2)

      arr(1,1) = 11
      arr(1,2) = 12
      arr(2,1) = 21
      arr(2,2) = 22

      do j = 1, 2

! The next source line should generate a compiler error because the ! loop index "j" is being redefined in the implied DO loop construct.

        write (*,*) (arr(i,j), j=1,2)
      end do
      end
