*> \par Purpose:
* =============
*>
*> \verbatim
*>
*> 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.
*> \endverbatim
*
* Arguments:
* ==========
*
*> \param[in] N
*> \verbatim
*> N is INTEGER
*> The number of characters in CA and CB to be compared.
*> \endverbatim
*>
*> \param[in] CA
*> \verbatim
*> CA is CHARACTER*(*)
*> \endverbatim
*>
*> \param[in] CB
*> \verbatim
*> CB is CHARACTER*(*)
*> CA and CB specify two character strings of length at least N.
*> Only the first N characters of each string will be accessed.
