-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft FORTRAN PowerStation for MS-DOS, versions 1.0, 1.0a 
- Microsoft Fortran Powerstation 32 for Windows NT, version 1.0 
- Microsoft FORTRAN Compiler for MS-DOS, versions 4.0, 4.01, 4.1, 5.0, 5.1 
- Microsoft FORTRAN compiler for OS/2, versions 4.1, 5.0, 5.1 
-------------------------------------------------------------------------------

SYMPTOMS
========

When a subroutine or an external function with entry points has an argument
passed by value, the compiler generates the following warning message for every
ENTRY statement in the code:

  warning F4201: ENTRY : formal argument : attribute VALUE : mismatch

RESOLUTION
==========

This warning message can be ignored, provided that there is no other problem
with the ENTRY statements.

STATUS
======

Microsoft has confirmed this to be a problem in the Microsoft products listed at
the beginning of this article. This problem was fixed in FORTRAN PowerStation
32, version 4.0.

MORE INFORMATION
================

The following sample code produces the F4201 warning message on compilation, but
will properly execute to yield correct results:

Sample Code
-----------

  C No compiler options required

        subroutine x(i)
        integer i[value]
        print *, i*3

        entry y(i)
        print *, i*7
        end

        program test
        integer j
        j = 5
        call x(j)
        j = 9
        call y(j)

        end
