Errorlevel Paradigm Behaves Differently in Windows NT 3.51

• Microsoft Windows NT Workstation version 3.51
• Microsoft Windows NT Server version 3.51

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%

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

     Return is: 1
     Return is: 3
