+     Concatenating variables will *NOT* work at all ...

On my Compaq 386 running DOS 3.31 and an IBM PC/AT running PCDOS 3.10 I
have no problem concatenating environment variables *within batch
files*. You can't do it from the command line though. Try the following
in your autoexec.bat:

set path=whatever_the_first_part_of_your_path_is
set path=%path%;whatever_the_next_part_of_your_path_is
...

Just don't make any single "set" command longer than 128 (see below).

+...the problem is the DOS
+limit itself.  DOS does not allow you to enter environment variables that are
+longer than 128 characters through DOS. ...

The problem is that MSDOS will not allow a command line over 128 characters
in length.
