TITLE   :BUG: Using "Save As" to Save File Causes Application Error
PRODUCT :Microsoft Fortran Compiler
PROD/VER::4.0
OPER/SYS:
KEYWORDS:kbide kbVCkbbuglist

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

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

SYMPTOMS
========

Saving a fixed-form source file that contains at least one physical TAB
character at the beginning of a source line, to a file with some other
non-default extension (such as .txt) by selecting Save As from the File menu in
Developer Studio, causes one of the following application errors at run time:

Under Windows 95:

   This program has performed an illegal operation and will be shut down. If the
   problem persists, contact the program vendor.

   Details:

   MSDEV caused an invalid page fault in module MSVCSRC.DLL

Under Windows NT version 3.51:

   The instruction at "0x00000000" referenced memory at "0x00000000".
   The memory could not be "read".

RESOLUTION
==========

Before saving the file using Save As option, change the file type to free- form
by right-clicking in the editor window and selecting Properties. Change the
Language combo-box option to Fortran Free. Then you can safely choose Save As
from the File menu.

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
================

Steps to Reproduce Problem
--------------------------

1. Open a source file that has an .for extension and verify that at least one
   source line begins with a physical TAB character. The Celsius.for file
   located in \Msdev\Projects\Celsius is formatted with TAB characters.

2. From the Developer Studio File menu, choose Save As, and save the file with a
   .txt extension. In some cases, Developer Studio (MSDEV) shuts down without
   warning, and in others, it hangs (stops responding) and' displays an
   application error.
