NAME
       TESTING/EIG/zslect.f

SYNOPSIS
   Functions/Subroutines
       logical function zslect (z)
           ZSLECT

Function/Subroutine Documentation
   logical function zslect (complex*16 z)
       ZSLECT

       Purpose:


           !>
           !> ZSLECT returns .TRUE. if the eigenvalue Z is to be selected,
           !> otherwise it returns .FALSE.
           !> It is used by ZCHK41 to test if ZGEES successfully sorts eigenvalues,
           !> and by ZCHK43 to test if ZGEESX successfully sorts eigenvalues.
           !>
           !> The common block /SSLCT/ controls how eigenvalues are selected.
           !> If SELOPT = 0, then ZSLECT return .TRUE. when real(Z) is less than
           !> zero, and .FALSE. otherwise.
           !> If SELOPT is at least 1, ZSLECT returns SELVAL(SELOPT) and adds 1
           !> to SELOPT, cycling back to 1 at SELMAX.
           !>

       Parameters
           Z

           !>          Z is COMPLEX*16
           !>          The eigenvalue Z.
