  We compare different next-to-leading order calculations of jet cross sections
in deep-inelastic scattering as implemented in the programs DISASTER++, DISENT,
JETVIP and MEPJET. In all phase space regions under study DISENT and DISASTER++
agree better than 2%. MEPJET shows systematic deviations of being typically
5-8% lower than the other programs. The JETVIP results show a significant
dependence on the phase space slicing parameter $y_{\rm cut}$. In the cases
where the $y_{\rm cut}$ dependence within $10^{-4} \le y_{\rm cut} \le 10^{-3}$
is smaller than 3% the JETVIP results are often comparable with the DISENT and
DISASTER++ results.
