Yes, COMMAND.COM chokes on this.  You only get a 128 character command
line.  Because %PATH% is replaced by your current path, DOS sees the
command as a full statement so this batch:

   SET PATH=C:\MENU
   SET PATH=%PATH%;C:\DOS

Looks like this to DOS:

   SET PATH=C:\MENU
   SET PATH=C:\MENU;C:\DOS

Therefore you don't get to input more than 128 characters.
