!> SGET40 tests STGEXC, a routine for swapping adjacent blocks (either
!> 1 by 1 or 2 by 2) on the diagonal of a pencil in real generalized Schur form.
!> Thus, STGEXC computes an orthogonal matrices Q and Z such that

!>     Q' * ( [ A B ], [ D E ] ) * Z  = ( [ C1 B1 ], [ F1 E1 ] )
!>          ( [ 0 C ]  [   F ] )        ( [ 0  A1 ]  [    D1]  )

!> where (C1,F1) is similar to (C,F) and (A1,D1) is similar to (A,D).
!> Both (A,D) and (C,F) are assumed to be in standard form

RMAX

!>          RMAX is REAL
!>          Value of the largest test ratio.
!> 

LMAX

!>          LMAX is INTEGER
!>          Example number where largest test ratio achieved.
!> 

NINFO

!>          NINFO is INTEGER array, dimension (2)
!>          NINFO( 1 ) = STGEXC without accumulation returned INFO nonzero
!>          NINFO( 2 ) = STGEXC with accumulation returned INFO nonzero

!>          KNT is INTEGER
!>          Total number of examples tested.
!> 

NIN

!>          NIN is INTEGER
!>          Input logical unit number.
