>(Dos documentation treats the Path command and set path= as synonomous.)

This has been proposed many times.  It does not work on any
version of DOS, on any 80x86 hardware I have ever seen!!

Why?

Because the expansion of the environment variable on the right side
of the assign is done before it is submitted to command.com and
therfore the 128 character truncation of the command line still
occurs.

For versions of DOS before 3.3, enved by Scott Robert Ladd can be
used from a batch file to set a path <= 256 characters.  Enved does
not work with DOS 3.3, at least for the versions with which I'm
familiar.

Can we please not propigate the same wrong answers ad nauseum?

Thanks!
