FIX: Incorrect F2560 with Adjustable Sized Arrays and /4Yb

The information in this article applies to:

• Microsoft FORTRAN PowerStation for MS-DOS, version 1.0

SYMPTOMS

Compiling an adjustable sized array with extended error handling (for example, /4Yb), which uses an expression for a bound, incorrectly produces the following error:

   error F2560: (array_name) : array bound used intrinsic call

RESOLUTION

Do not use extended error handling when compiling adjustable sized arrays that are dimensioned with an expression.

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.

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.

MORE INFORMATION

The sample program below demonstrates the problem when compiled with FORTRAN PowerStation:

Sample Code

$debug

       SUBROUTINE TEST(N,X)
       INTEGER N
       REAL X((N+1)/2) ! Expression dimensions adjustable array X
       X((N+1)/2)=1
       RETURN
       END
