/*  -- LAPACK auxiliary routine (version 2.0) --   

       Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,   

       Courant Institute, Argonne National Lab, and Rice University   

       September 30, 1994   

    Purpose   

    =======   

    LSAMEN  tests if the first N letters of CA are the same as the   

    first N letters of CB, regardless of case.   

    LSAMEN returns .TRUE. if CA and CB are equivalent except for case   

    and .FALSE. otherwise.  LSAMEN also returns .FALSE. if LEN( CA )   

    or LEN( CB ) is less than N.   

    Arguments   

    =========   

    N       (input) INTEGER   

            The number of characters in CA and CB to be compared.   

    CA      (input) CHARACTER*(*)   

    CB      (input) CHARACTER*(*)   

            CA and CB specify two character strings of length at least N. 

            Only the first N characters of each string will be accessed.
