Information for running the batch file is loaded in the lowest free memory
available. This will be right next to the memory block allocated for the
master copy of the environment thus blocking any growth. The SET command is
an internal command which does not require anything to be loaded in memory.
The same situation occurs if you have loaded any TSR programs. They will
prevent MS-DOS from being able to expand the environment beyond its initial
allocation even from the command line.
