Se '~beta/sysutils/v1.6/envstring':

expandEnvVar: 
  (* Expands text containing substrings of the form $(VAR) to the value
   * of the corresponding unix-environment variable.
   * 
   * E.g., if the unix-command printenv says
   * HOME=/users/cn
   * SHELL=/bin/csh
   * USER=cn
   * 
   * then                  is expanded to
   * 
   *  $(SHELL)               /bin/csh
   *  $(HOME)!$(USER)        /users/cn!cn
   * 
   * (if an environment variable is specified, which is not set, then the
   * virtual pattern defaultvalue is called. This allows the programmer to
   * specify default-values for not-set environment variables.
   *)
