TITLE   :BUG: FOR1252 Error USE of Module in Internal Module Procedure
PRODUCT :Microsoft Fortran Compiler
PROD/VER::4.0
OPER/SYS:
KEYWORDS:kbFortranPS kbLangFortrankbbuglist

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

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

SYMPTOMS
========

Using a user-defined data type defined in one module at another module's
internal procedure level where the internal procedure defines the behavior of
either the INTERFACE OPERATOR(+) or INTERFACE OPERATOR(-) specified by the
MODULE PROCEDURE statement, causes the following internal compiler error:

   error FOR1252: internal compiler error detected between % and X

   Internal Error -- please report this bug Command line error D2013: internal
   compiler error.

RESOLUTION
==========

Specify the USE of the user-defined data type at the module level not at the
module's internal procedure level.

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.
