[all about the full pathname of the program following the environment]
}Why don't all programs use the sensible approach [of finding their directory]?
}is because this is an undocumented (an therefore unguarenteed) feature?  May-

It is also not around in DOS 2.x, and a lot of people still run 2.x.  The 
sensible thing to do (like Turbo C does) is to use this feature if running
3.x, and require some other way of finding the support files otherwise.
