• 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

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.

MORE INFORMATION
