We report the final results on all particle spectrum and on average mass coming from full data obtained by ten RUNJOB campaigns performed from 1995 up to 1999. We show the all-particle spectrum and the average mass of primary cosmic rays in the energy region 20-1000 TeV/particle. In this report we compare our results to those obtained by other direct measurements and also indirect measurements. The intensity of the RUNJOB all-particle spectrum is 40-50% less than those obtained by JACEE and SOKOL, while the slopes of the spectrum seem to be in agreement in energy range more than 100 TeV/particle. Comparing to indirect measurements, our intensity is similar to lower intensity group such as CASA-MIA, not KASCADE. The average mass remains almost constant up to ̃ 1 PeV, whereas the JACEE data suggest a rapid increase with primary energy beyond 100 TeV/particle. In EAS data there is also a considerable disagreement in the indirect data between KASCADE and CASA-MIA, with the former connecting smoothly to the RUNJOB data, and the latter connecting to the JACEE data around 2 PeV.
