ID: Q111429

The information in this article applies to:

Microsoft Windows NT operating system version 3.1
Microsoft Windows NT Advanced Server version 3.1

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
