SUMMARYThis article outlines some of the differences between the retail and dubugging (debug) versions of Microsoft Windows version 3.1. MORE INFORMATION
The retail version of Windows 3.1 can be transformed into the debug
version by using files that are provided with the Windows 3.1 Software
Development Kit (SDK).
The .SYM files are symbol files that contain symbolic information that
the SDK utility programs, CodeView (CVW.EXE), and Windows 80386 Debugger
(WDEB386.EXE) use to locate program modules, global data in an executable,
and other debugging information. The .SYM files can remain in the Windows
\SYSTEM directory (they do not affect the performance of Windows when the
retail Windows 3.1 system files are being used). The .DLL and .EXE files
are special debugging versions of the normal files that replace the
corresponding retail Windows files in the Windows \SYSTEM directory.
Below is a list of the normal files that must be present in the Windows \SYSTEM directory to run the retail version of Windows 3.1:

These messages appear as follows:ENHANCED MODE DEBUG Windows 3.1-or- STANDARD MODE DEBUG Windows 3.1 How to Switch Between Debug and Retail WindowsThere are two batch files, D2N.BAT and N2D.BAT, that are provided with the SDK that allow you to switch between the retail and debug versions of Windows 3.1. These files are normally found in the WINDEV\BIN directory. N2D.BAT is used to convert retail Windows into debug Windows. D2N.BAT is used to convert debug Windows to retail Windows.Changes Made to SYSTEM.INIThe following lines are added to the SYSTEM.INI file when the SDK is installed:
