I ran across this bit in Mike’s code, and couldn’t help but smile:

IF totalEnergy < 0 THEN
    totalEnergy := 0;   {this line saved my sanity! Believe me, shieldLevel _can_ be negative}

I’ve met few programmers who don’t put funny comments in their code now and again. For example, here’s one of mine from the warp drive subsystem:

if (enteringWarp && velocity > minWarpVelocity)     // We hit 88 miles per hour! Activate the flux capacitor!

I pity anyone whose code review guidelines forbid them from doing things like this. When trying to figure out someone else’s code, a little humor is desperately needed.
