system variables in DOS clisp

[John Levine <johnl@dai.ed.ac.uk>]

Hi,

Is there any way of accessing DOS variables from inside the DOS version
of CLISP? That is, I want to do something like this:

  c:\> set spong="c:\wibble\wombat\"
  c:\> clisp

  > (setq *path* (get-dos-variable spong))
  "c:\wibble\wombat\"
  > (load (format nil "~Acode.lsp" *path*))

  etc...

Thanks,

John
