I suppose that you have tried this two different ways and have not 
noticed.  There are two ways to set the path.  One is with the PATH
command and the other is with the SET command.  PATH is used as:

	PATH=\WHATEVER;...

whereas SET is used as:

	SET PATH=\WHATEVER;...

I suspect that batch files can interpret the percent signs around your
variables during a SET command but not a PATH command.

I have read that the PATH command is provided for compatibility with
DOS 2.x since the SET command does the same and more.  I have also
read that the PATH command is "better" or "safer" than the SET
command.  Does anyone know why this would be?
