LOGICAL FUNCTION LSAMEN( N, CA, CB )
*
* -- LAPACK auxiliary routine (version 3.0) --
* Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,
* Courant Institute, Argonne National Lab, and Rice University
* September 30, 1994
*
* .. Scalar Arguments ..
CHARACTER*( * ) CA, CB
INTEGER N
* ..
*
* 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.

$ GO TO 20
*
* Do for each character in the two strings.
*
DO 10 I = 1, N
*
* Test if the characters are equal using LSAME.
*
IF( .NOT.LSAME( CA( I: I ), CB( I: I ) ) )
