/*  -- LAPACK auxiliary routine (version 3.1) --   
       Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd..   
       November 2006   


    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.
