We report on preliminary measurements of the central ({vert_bar}{eta}{vert_bar}<0.5) inclusive jet cross section and the dijet angular distributions ({vert_bar}{eta}{vert_bar}<3) at {radical}s=1.8 TeV. The data were collected during the 1992-1993 and 1994-1995 runs at the Fermilab Tevatron p{anti p} Collider with the D0 detector. The measurements are in excellent agreement with next-to- leading order (NLO) QCD. Given the assumptions implicit in the theoretical models, we exclude quark compositeness to the 95% confidence level on a scale of {Lambda}{sub +}=2 TeV.
