  Builtin Function



      SSyynnooppssiiss
        Get an environment variable

      SSyynnttaaxx
        getenv ( _N_A_M_E )

      DDeessccrriippttiioonn
        Getenv searches the current environment for a variable with name
        _N_A_M_E. The value of the environment variable is returned as a
        string.

        Exactly how getenv behaves is depends upon the underlying
        operating system implementation. On UNIX system getenv will
        return a NULL string if the environment variable does not exist.
