Question on EMC

Hi All:
One of my Mach1 users has asked what posts for various programs can use
the rotary axis, due to the fact that they do not rollover to 0 at 360
degrees. The Posts he's using can't seem to handle the math. Mach1 uses the
EMC interpreter so I thought I'd ask the experts.

Is the fact that EMC's rotary axis work in a linear fashion a problem?
Does anyone else have this problem in rotary work. The general concensus
among users seems to be that they don't want the rotaries to rollover at
360, but I can see this users point. The distance from 350 degrees to 20
degrees really SHOULD be a command like A+30.0 instead of A380, but if the
posts support A380 there should be no problem. Do the current posts you use
support the rotary axis in a linear fashion or is EMC configurable( if so I
haven't seen the code) to 360 rollover with + and - G-Code commands for
direction?

Thanks,
