    What is the relationship among dos4g.exe,stub_4g2.exe and DOS4G=QUIET ?

    Dear all,

    I got one open-source watcom C's code and want to know the relationship among these 3 :

    dos4g.exe ( I know this is a DOS extender )
    stub_4g2.exe ( <- ??? )
    DOS4G=QUIET in xxx.bat ( means ?)

    ( I plan to write a utility in watcom c++ and wish to run it in "protected" mode...)

    Could anyone tell me how to write the xx.bat correctly and how to use dos4g.exe ?

    Thanks in advance

    dos4g.exe
    dos4g is, as you said already, a 32bit dos extender

    DOS4G=QUIET
    You can set the environment
    variable DOS4G=quiet in your AUTOEXEC.BAT file to
    eliminate the DOS extender's copyright notice.

    1. Does the statement "DOS4G=QUIET" (in xxx.bat) mean "execute dos4g.exe" and "tell it not to show copyright" ?

    2. stub_4g2.exe is ? I found no information of it...

    Sadly, Tenberry.com is gone, now. However, The Wayback Machine has copies; these are the corrected URLs:

    A bit more googling finds the sad reason that Tenberry.com is gone: founder/owner Terry Colligan has died, at age 70. Here's an obituary:
