He forgot to tell you that this must be done within a batch file.  DOS
is very stupid.  Whomever decided to only do environment substitutions
and the like from batch files (and not the keyboard) should have been
shot, but we have to live with it.

I believe it will work if you throw it into a .BAT file, though I have
yet to try it.  You might also have length limitations imposed by DOS's
COMMAND.COM interpreter on environment substitutions, but I was unable
to find information about one in the Tech. Ref. manual.
