DOCUMENT:Q94412 19-NOV-1999 [msdos] TITLE :AUTOEXEC File Is Not Processed Running 3rd-Party Shell PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.0,6.2,6.21,6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 6.22 ------------------------------------------------------------------------------- SUMMARY ======= Some third-party command shells (such as NDOS or 4DOS) do not require the /P switch (which specifies the command shell is permanent). As a result, if you use a third-party shell without the /P switch, and set environment variables from your CONFIG.SYS file or use MS-DOS 6 or later startup menus, your AUTOEXEC.BAT file is not processed when you start your computer. MORE INFORMATION ================ Third-party command shells that do not require the /P switch check to see if an environment has been created. If it has, they do not call the AUTOEXEC.BAT file. If you use the MS-DOS 6 startup menu feature or you set environment variables (such as PATH or PROMPT) in your CONFIG.SYS file, an environment is created and the AUTOEXEC.BAT file is not processed.
