Scale invariant presentation of inclusive spectra in terms of light front variables is proposed. The variables introduced go over to the well-known scaling variables and in the high pz and high PT limits respectively. Some surface is found in the phase space of produced -mesons in the inclusive reaction at 22.4GeV/c, which separates two groups of particles with significantly different characteristics. In one of these regions a naive statistical model seems to be in a good agreement with data, whereas it fails in the second region.
