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.



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.
