KEYWORDS:

----------------------------------------------------------------------
The information in this article applies to:
 
 - Microsoft Windows NT operating system, version 3.1

When you log on to a Windows NT machine, Winlogon processes the
AUTOEXEC.BAT file to set your environment variables and the PATH.
 
However, the following restrictions apply to all SET statements:
 
 - Conditional set ("IF") statements are not processed.
 
 - Environment variables cannot be removed (unset). For example, "SET
   WORKDIR=" does not remove the WORKDIR environment variable.
 
In short, only SET and PATH statements are processed.
 
Additional reference words: 3.10 unset
