Recent progress in understanding da*a on two 'o three particle hadron
reactions is described. The use of an s-channel azimuthal angle selection
is advocated to identify and separate different exchange mechanisms which
contribute to the same final state at low subenergy. Solutions to the neutral
Q cross-over problem in the Dl!ck undel are discussed, and experimental tests
are proposed. Methods are offered for enhancing resonance signals in the
presence of a large Deck exchange background. The need for absorptive cor-
rections to the usual Deck model is stressed in the light of new FNAL data
on diffractive neutron dissociation and ISR data on proton dissociation.
Results of an explicit absorbed pion exchange Deck model calculation are
compared with data,
