DOCUMENT:Q111429 08-AUG-2001 [winnt] TITLE :SET Batch File Command Resets Error Levels PRODUCT :Microsoft Windows NT PROD/VER:3.1 3.5 OPER/SYS: KEYWORDS:kbenv kbinterop ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 3.1 - Microsoft Windows NT Workstation version 3.1 - Microsoft Windows NT Advanced Server, version 3.1 - Microsoft Windows NT Workstation version 3.5 - Microsoft Windows NT Server version 3.5 ------------------------------------------------------------------------------- SYMPTOMS ======== After you upgrade to Windows NT, some of your MS-DOS batch files may fail to work as expected. This is due to how the SET command's functionality has changed. Under MS-DOS, the SET command did not reset the error level, enabling you to SET variables and handle error levels later in your batch files. This problem also exists in the following batch file commands: PATH, DPATH, and PROMPT. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT Workstation and Windows NT Server version 3.5. This problem was corrected in the latest U.S. Service Pack for Windows NT version 3.5.
