  Loop calculations in light-cone gauge must confront many technical
complexities. We offer here a compendium of detailed light-cone calculations in
Yang-Mills theories (with no matter fields). We consistently regulate the p^+=0
singularities through discretization of the p^+ component of momentum. Although
it is more cumbersome than the Mandelstam-Leibbrandt prescription, this choice
has the virtue of employing only positive norm states, retaining manifest
unitarity. Some of the results given here are useful in a forthcoming paper
with D. Chakrabarti and J. Qiu on scattering of glue by glue, specifically the
results for the gluon self-energy and one-loop vertex corrections.
