APPNOTE: QuickWin Unformatted File/Huge Data Items Patch

ID: Q75457

The information in this article applies to:

Microsoft FORTRAN for MS-DOS, version 5.1
Microsoft FORTRAN for OS/2, version 5.1

SUMMARY

An application note is available that explains how to correct a problem with writing huge data items to unformatted binary files within FORTRAN version 5.1 QuickWin. When writing a data item greater than 64K to an unformatted or binary data file from within QuickWin, an Unrecoverable Application Error (UAE) may result.

Application notes can be obtained by calling Microsoft Product Support Services.

This file has been removed from the Microsoft Software Library but can be requested by calling Microsoft Product Support Services.

 --------------------------------------------------------------------

This application note illustrates how to modify the FORTRAN version 5.1 Windows run-time library LLIBFEW.LIB to correct a problem with HUGE data items and unformatted or binary files.

A program compiled with FORTRAN 5.1 for use with Windows can cause an unrecoverable application error (UAE) in Windows. A UAE may occur if the program opens a file whose form is either binary or unformatted and then READs or WRITEs to that file using elements of HUGE arrays that are beyond the first 64K of the array.

Included on the enclosed "Patch for QuickWin Unformatted File and HUGE Data Problem" disk are two replacement object modules for two object modules in the Windows library LLIBFEW.LIB. These replacement modules correct the above problem.

The files on the enclosed disk are:

APPLOAD.OBJ
RELOC.OBJ

To make a patched version of the Windows library LLIBFEW.LIB, copy APPLOAD.OBJ and RELOC.OBJ from the enclosed disk to the directory where LLIBFEW.LIB is located. Then, execute the following command:


    lib llibfew.lib -+appload.obj -+reloc.obj;

This command will use the Microsoft Library Manager to replace the existing object modules in the library with the new patched versions of the object modules. You can then delete APPLOAD.OBJ and RELOC.OBJ from your hard disk.
