Below a (comparatively large) measure of non-hermiticity Y=Y(0)((crit)) 0 of a PT symmetrically complexified square well, bound states are constructed non-numerically. All their energies prove real and continuous in the (Hermitian) limit Z--) 0. Beyond the threshold Y(0)((crit))(and, in general, beyond Z(m)((crit)) at m=0,1,...) the lowest two real energies (i.e., E-2m and E2m+1) are shown to merge and disappear.
