I don't understand this.  One of the nice things about 4dos is that there
are enough primitives for manipulating the environment that hacks like this
are not needed.  Since these programs diddle with the parent environment they
should work with command.com also (give or take some tweaking)

If all you want to do is temporarily change the path, why not just
setlocal
set path=%new-entry%;%path%
....
endlocal

If you want to chop stuff out of the middle of the path, or other complex
operations, let the program spit the revised value to stdout, then
do 
manglepath  args | input %%path
- totally legal, no hacks.

Also, these programs uppercasify the entire environment, which breaks a lot
of stuff that depends on the case of the values (only the NAMES should be
upper case)
