  • Config.sys and missing Shell Statement

    This is the first time I've encountered this problem. In my DOS app,
    I have this SHELL statement:

    Shell "COPY .\Template\Measured.Set .\Template\Measured.Bak >Silent.tmp"

    The .\Template\Measured.Set file exists and .\Template\Measured.bak
    does not. On most Win 9x machines the program runs without any
    apparent problem. However, I encountered a computer a couple of days ago
    with Win 98 that would generate an Error 76 at this statement.

    After changing the obvious code many times without any success, I
    decided to create a batch file with the above "copy" statement in it.
    On executing it the OS reports that C:\DOS\ cannot be found.

    I assumed that WIN 9x already knew where it had installed
    Well, I obliged and put a copy of in a C:\DOS folder and now
    the Shell statement works (on that computer.)

    A better fix would be to put a SHELL statement inside CONFIG.SYS
    with the path to the file.

    Was I just lucky and on every other computer the program runs on there just
    happens to be a file in the root directory of the boot drive?

    It sounds to me like you originally formatted the drive under
    DOS 6.x or something similar then installed Windows. Under DOS,
    COMMAND.COM is usually located in the "C:\DOS" sub-directory.

    When Windows 9.x is installed the new COMMAND.COM is usually
    located in "C:\WINDOWS" or "C:\WINDOWS\COMMAND" sub-directory,
    leaving the orginal "C:\DOS\COMMAND.COM" unchanged or at least

    During the install process, Windows updates the line it needs to
    convert in the CONFIG.SYS and AUTOEXEC.BAT files. If it does not
    need to convert a line for its own use, it leaves it alone. That
    leaves you to convert lines manually. Converting these lines
    manually is usually a big fat pain but it's a necessary evil.

    There are no atheists in a fox hole or the morning of a math test.
    If my flag offends you, I'll help you pack.
