re: IJK interp

Ballendo,

So "FROM" Current position is the same as "TO" the center. Got it. So
my flavor is "Fanuc". I kinda thought it might be.

The 67.5 was part of MY comment ('C' code), these two lines draw a 360
degree circle, starting at the 67.5 degree position. One of my early
tests. These two lines were actually hard coded in a table of many
selections, so that I could quickly command an arc for test purposes.
Kinda like a "canned" routine.
