SYMPTOMS
When you assign an attribute to multiple variables with the same !ms$attributes metacommand in an interface block of a free-form source code file, only the first variable is given the attribute.



RESOLUTION
Do one of the following to work around the problem:


 * Specify the !ms$nofreeform metacommand for the interface block. -or-


 * Use one !ms$attribute metacommand for each variable. -or-


 * Use a fixed-form source code file.



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
In the following sample code, when the compiler parses the line containing the !ms$attributes metacommand in the interface block, only the variable "i" is correctly assigned the value attribute. The variable "j" is not processed and therefore retains the default Fortran reference attribute.

Sample Code to Demonstrate Problem and Workarounds
! Compile options needed: none ! required extension: .F90 program test

! uncomment the following line for the first workaround: !!ms$nofreeform interface subroutine thesub(i, j)                 integer i, j ! comment the following line for the second workaround: !ms$attributes value :: i, j ! uncomment the following two lines for the second workaround: !                  !ms$attributes value :: i !                   !ms$attributes value :: j              end subroutine end interface ! uncomment the following line for the first workaround: !!ms$freeform

integer i, j         i = 1 j = 2 call thesub(i, j)     end

subroutine thesub(i, j)         integer i, j          !ms$attributes value :: i, j          print *, i, j         ! should print "1 2" end subroutine
