Sorry Gary,  this soulution does not work.  DOS does not do
expansion of $p.  The $p is only meaningful to the PROMPT command.
The result of your solution is that 'prompt' contains the literal
'$p'
 
Also beware of surrounding the equal signs in SET commands with spaces.
The are taken literally and become part of the envar name. So...
 
      set foo=bar  and  set foo = bar
 
create 2 different envars.  And if you write batch files that check
for envar contents, it will barf on one of those.  The convention
is not to include any spaces in the SET arguments.  I've seen many
a batch file crapout because of this,  usually with a puzzled user
on the other end.
