Set PATH sets the environment variable PATH, this variable is checked 
when looking for executables.

The %PATH% at the end of this line refers to the existing PATH variable, 
ie the PATH is effectively having the bit at the front added on.

Put 

SET PATH=C:\NUPROGS\DJGPP\GNU\EMACS;%PATH% 

in your autoexec either in place of or in addition to the line above 
depending on whther you want both of these paths or just the latter. You 
can also set the path at the command line or via another batch file in 
the same way.
