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.
Parameters
[in]N
          N is INTEGER
          The number of characters in CA and CB to be compared.
[in]CA
          CA is CHARACTER*(*)
[in]CB
          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.
