SYMPTOMS
The value returned to the operating system by a 16-bit application when it closes is called an error level. The values that Windows NT 3.51 returns is different than those returned by OS/2 1.3 and Windows NT 3.5. For example, create a TEST.CMD file with the following text:

@echo off

return 3

if errorlevel 3 set x=3

if errorlevel 2 set x=2

if errorlevel 1 set x=1

echo Return is: %X%

return 3

if errorlevel 1 set x=1

if errorlevel 2 set x=2

if errorlevel 3 set x=3

echo Return is: %X%

NOTE: RETURN.EXE is just a simple program which performs exit(atoi(argv[1])).

If you run TEST.CMD in OS/2 1.3 and Windows NT 3.5, the following results appear:

Return is: 3

Return is: 1

If you run TEST.CMD in Windows NT 3.51, the following results appear:

Return is: 1

Return is: 3

This problem has been corrected in the latest Service Pack for Windows NT version 3.51.
