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

[jimmyliao]

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:
